Can you use the GALLERYIMG="no" for images in CSS? How would you do that? Sorry this is a stupid question.

i don't know of any css equivalent.

css is generally a formatting procedure. something that is done to a physical attribute of an object.

galleryimg is probably a proprietary (IE only) element and seems to be a non-physical.

Gallery IMG is the little bar that shows up on some IE browsers asking to save or open files. I guess you're right, sadly.
