What should happen when the user double-clicks on an image-file in your gui. In some cases it is logical to show the image in an image-viewer... but it is no need of linking all kinds of extensions to different programs. - It is already done by the filebrowser. Puppy uses 'rox' and if you execute ##rox /path/image.png## the image will show up in the defined viewer. Just as simple as that.
