It would be really useful if the user could identify the taxon of an image in a panel. For example, in the dungbeetle site I was looking for a nice panels page for illustration. I kept getting empty hits on the classification, so I clicked on 'Coleoptera' and got a bunch of nice images in the panel. Unfortunately I couldn't home in on them because I didn't know what they were.

There is also a need to be able to carry image meta-data, particularly attribution information, with the image on download.
