      Here's a discreet way of downloading an image file from a url on Windows only - using vbs...

      strFileURL = "http://www.it1.net/images/it1_logo2.jpg"
      strHDLocation = "C;\Temp\it1_logo2.jpg"
      Set objXMLHTTP = CreateObject("MSXML2.XMLHTTP")
      objXMLHTTP.open "GET", strFileURL, false
      objXMLHTTP.send()
      If objXMLHTTP.Status = 200 Then
        Set objADOStream = CreateObject("ADODB.Stream")
        objADOStream.Open
        objADOStream.Type = 1 'adTypeBinary
        objADOStream.Write objXMLHTTP.ResponseBody
        objADOStream.Position = 0    'Set the stream position to the start
        Set objFSO = Createobject("Scripting.FileSystemObject")
      If objFSO.Fileexists(strHDLocation) Then objFSO.DeleteFile strHDLocation
        Set objFSO = Nothing
        objADOStream.SaveToFile strHDLocation
        objADOStream.Close
        Set objADOStream = Nothing
      End if
      Set objXMLHTTP = Nothing
      

      Make a copy of this text in a file that's called say
      C:\Temp\urldownloader.vbs
      or another Temp folder etc...
      Change the first two lines of the text to be the url [I've used a known image_file simply to show that it works] and the folder+filepath to save that file to - in this example I put it into C:\Temp\ too using the same file_name...
      Now run it from within Ruby
      UI.openURL("C:\\Temp\\urldownloader.vbs")
      In Ruby wait till the file arrives - timeout after a while ?
      To tidy up you can delete the temp file...
      It works - I have run it successfully...

        Nothing is easy. πŸ˜†

        You have the right idea, but I think you may need to add more locations to make it complete. If you check the $LOAD_PATH of your installed Ruby, you'll find it has more locations than just those you listed. See Dan's post on the subject. We should have more success using the installed Ruby since we now have 1.8.6 in SketchUp and an installable 1.8.6

          VBScript will run in the WebDialog, so you could eliminate the external file. But I would still try to follow Thom's advice, use JavaScript, and pass the data to the Ruby plugin to save it on disk.

            My 'vbs' method means you don't actually need a web-dialog running at all.
            You can download images from a url with it [on PC] irrespective of what the Ruby script is doing or has as an interface... πŸ˜•

              Exactly.

              The most beneficial result from this thread would be a cross-platform download library which could be used for images or anything, really.

                But the original inquiry was 'for PC' ?
                A pure Javascript version can't work [?] - because of security issues there is no plain 'save' - only 'save_as', to you ensure you know what's going on with downloading things off the www onto your PC...
                The 'vbs' method will work for PC - there's probably an equivalent AppleScript [type] method for the MAC... but I can't see how a 'cross-platform' version might work πŸ˜•
                Java is inherently 'limited' as I said...

                  I think it can. There is no save or save as in JavaScript. You can save to disk using JavaScript, but there isn't a cross-platform solution. On Windows, you would use a FileSystem activex object. The same scripting host that rtuns the .vbs can run .js also.

                  But, the XHR is available on all (important) browser platforms. So a cross-platform solution is to use a WebDialog, fetch the file using the XHR, then pass it to the ruby plugin for saving to disk.

                  This small library is a good example of using a XHR cross-platform:
                  http://code.google.com/p/microajax/

                  
                  if (window.ActiveXObject)
                  return new ActiveXObject('Microsoft.XMLHTTP');
                  else if (window.XMLHttpRequest)
                  return new XMLHttpRequest();
                  return false;

                    What's this then ?
                    <a href="java script&#058;void(0);" onclick="document.execCommand('SaveAs',true,'http://fileden.com/somefolder/some file.mp3');">download</a>
                    There's just not a 'Save' version ???

                      I've never heard of "execCommand" before, but I'd be surprised if it were cross-platform. If it existed, we probably wouldn't be having this discussion.

                          While the JS debate rages, I've been playing with what can be done with ruby (being single-minded/stubborn/lazy)

                          I've updated my !loadpaths file to match dan's latest http://forums.sketchucation.com/viewtopic.php?f=180&t=29412&hilit=load+path#p257058
                          and when I try a couple of things I get this response:
                          require 'net/http' Error: #<LoadError: C:/ruby186/lib/ruby/1.8/net/protocol.rb:21:inrequire': No such file to load -- socket>
                          C:/ruby186/lib/ruby/1.8/net/protocol.rb:21
                          require 'date/format'
                          true`

                          Any ideas on why net/http fails, but date/format works?

                          I'm sure it will take some clever file management, and refresh cycle control etc, but it'd be cool to be able to specify a url to get a texture from. That'd open up a load of opportunities for data vis etc.

                            That means it couldn't find the file (socket.so) in the load path.

                            For a short-term solution, you could try to copy socket.so to the Plugins folder.

                              It's HTML 5 me thinks. And seems Microsoft may have added a bunch of standard CommandIDs without getting them approved by the web community (as usual.) The spec implies browser specific IDs should have a prefix like "IE-", but MS has been doing this 'arm-twisting' for years.

                              See: http://www.w3.org/TR/html5/author/dom.html#execCommand

                              MSDN: http://msdn.microsoft.com/en-us/library/ms536419(v=VS.85).aspx
                              and MS' command IDS: http://msdn.microsoft.com/en-us/library/ms533049(v=VS.85).aspx
                              ~

                              I'm not here much anymore.

                                Hello!

                                Has anyone made any progress on a simple, cross platform solution to this in the past few months?

                                Thanks,

                                  I solved in on Windows platform.
                                  In my script installation I included ruby lib files needed for http, so users will have them after installing script.
                                  The code followed in script:

                                  $LOAD_PATH << File.join(MY_PLUGIN_HOME, "bin", "rblib")
                                  Sketchup::require 'uri'
                                  Sketchup::require 'net/http'

                                  Installer for MAC OS should have different ruby library files I think. I haven't MAC yet, so I can't tell any more. Let me know if you solve it.

                                      Digging up this old thread because I'm trying to do almost the same as the OP. Since the last post in this topic, Ruby has been updated so I'm hoping its more simple now.

                                      I have been trying several methods. This code saves the image in the local documents folder so I could pick it up there etc.

                                      require 'net/http'
                                      Net;;HTTP.start("www.google.nl") do |http|
                                          resp = http.get("/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png")
                                          open("googlelogo_color_272x92dp.png", "wb") do |file|
                                              file.write(resp.body)
                                          end
                                      end
                                      puts "Done"
                                      

                                      Problem is, my images need a different type of url. Something like:
                                      https://url/coordinates/?key=1234abc&index=0
                                      This sort of link doesn't work in the code above.

                                      Another method I'm trying is loading the image in a webdialog and then grabbing it from Ruby.

                                      The test html code (the url could easily replaced with the actual https code) is:

                                      <!DOCTYPE html>
                                      <html><head></head><body>
                                      <img id ="webimage" src = "https://www.google.nl/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png">
                                      </body></html>
                                      

                                      And to grab the image in ruby:
                                      img = @wd.get_element_value('webimage')

                                      Of course this doesn't work because the image isn't a value. I'm stuck.

                                      Anyone has a suggestion? That would be very welcome.

                                        unless fail
                                        	begin
                                        		File.delete(file) ### in case it exists

                                        	rescue Exception => error
                                        		puts "#{error}"
                                        	end
                                        end
                                        
                                        

                                        It should work with a 'php' formatted URL, but remember that then you need to parse out the file name another way. Perhaps [assuming 'key=' gives the file name] split the URL at '?', then take [1], then split at '&', then find the array element starting "key=", then split that at '=' and then [1] is the file name given by 'key=' ?
                                        I also saved the downloaded image file in the 'current directory', but you can of course choose any other folder you want...

                                          Thanks for the reply TIG. Your code does download a file but when trying to open it I get:
                                          Decode Error! Invalid or unsupported PNG file

                                          Edit:
                                          I was also trying with net/http. It does work with simple files but the actual https request still fails.

                                            In case someone runs into the same question. It seems to work now.

                                            require 'net/http'
                                            require 'tempfile'
                                            
                                            uri = URI('https://www.google.nl/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png')
                                            
                                            model = Sketchup.active_model
                                            materials=model.materials
                                            m = materials.add "Test Color"
                                            loc = ''
                                            
                                            begin

                                            	Net;;HTTP.start(uri.host, uri.port,
                                              ;use_ssl => uri.scheme == 'https') do |http|
                                            	  http.request(request)
                                            	  response = http.request request # Net;;HTTPResponse object
                                            		file = Tempfile.new(['foo','.png'], Dir.tmpdir, 'wb+')
                                            	  begin
                                            			file.binmode
                                            			file.write(response.body)
                                            			file.flush
                                            			loc = file.path.gsub("/", '\\\\\\')
                                            	  ensure
                                            			file.close
                                            	  end
                                            	end
                                            rescue Exception => e  
                                              puts e.message 
                                            end
                                            
                                            m.texture = loc
