Yes - on the right hand side next to the text of the image, it gives some information about the image, including gallery, genre, upload date and other statistical info. So if you submit to the critique gallery it will say  'Critique'  rather than 'Poser' or 'Vue'  etc.
Also if you browse the new submitions and specify the poser gallery you will not get the images in the critique group (and vice versa)
Did I say before you sould be able to specify more than one?  :)

"I paint that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence."
Man Ray, modernist painter
