Place Decal on curved surface

SU8.0.3117 on Windows XP
I want to apply an image (not a texture) to a compound-curved surface. I found some instructions in the Help file under : << Can I Drape a raster image in a half sphere? >>. I followed the instructions from Gully Foyle as best I could.
I copied the yellow fabric face to a new group, revealed hidden geometry, and selected one facet in the middle of the surface. Next, I exploded the image [shown lying on the deck in the picture below], sampled it, and used the bucket to apply it to the selected face. Then I turned off hidden geometry, and applied the image to the rest of the surface.
The logo appears on the surface, but as a multi-image texture. I imported the JPG file "as image" instead of "as texture". When I context click on the applied images I don't see an option to Position Texture, or any way to edit the image. So how can I do away with all the extra logos?
I was hoping there might be a Ruby script to simplify this process, but I haven't found one. Any suggestions?

SU tiles textures, so you'll need to make the border around the graphic you wish to see large enough to prevent the repeating tiled image from being visible. Also, try "projected" for the image.

Thanks for the reply. I tried the "projected image" technique, but I still get the same results. The single image is painted over the whole surface as a texture. But, even as a texture, I can't find a right-click command to "Position" the image, or to crop out the copies I don't want.
How can I draw "a border around the graphic" or on the surface to contain just one copy of the image? I tried selecting just a few facets with "Hidden Geometry" turned on, but that still didn't work. The original border was omitted when I exploded the image.
Maybe I'll try the Manipulating an image as material using Free Pin mode next.

You have to have the lines on the the surface so that you have a smaller area to paint with the logo. There are a number of ways to draw the lines on the surface. You could draw a rectangle and use Push/Pull to push it through the curved surface and then use Intersect to place lines on the surface. You could use Tools on Surface or just draw the lines by hand.
Since the surface is curved, you won't be able to position the material using the pins or the other position adjustment tools.
