Any information is better than no information.  It puts the images in a
rudimentary context (this is image 4 of 9 on the page).  A non-visual user
still may have no idea what the image really is, but can be told that image
number 4 at the "photo-upload site" is of their grandchild, and they could
then copy the file to a flash drive, and have the photo printed and framed
for when visitors come over to visit (just to make the scenario "real").

(slightly modified from an actual Flickr page)

...is the image the Googleplex, or you working at your desk?
