It would be great to see a list of the last ten (or so) pictures viewed so I could go back quickly to a specific one. At the moment (unless I am missing something) I have to remember to make a note of the artist and then go through all of their pictures. ( I sometimes am inclined to comment but want to think about it for a bit so I continue to look around .. hit other sites etc.)

..and.

Is it possible to automatically subscribe to a picture discussion when I make a comment?
I sometimes want to know opinions on 'my' opinions and suggestions and I always forget to subscribe and then I cant find the picture (see above suggestion). Using the back button is sometimes an option but not always.
