No - the exported DAE [text-format] always has its related image-files in a folder of the same-name - but of course you can then make a ZIP of the DAE and its folder to send on to someone - if that is your issue... In passing... if you exporte a KMZ, then that is effectively a renamed ZIP, containing a DAE file and its images-folder inside a 'models' subfolder, with a KML file at its base level.
