Many Flickr group's administrators as a rule of membership want to copy and past a signature (often with a picture) to show that photo has been seen inside the group stream, to prove their group is alive and fruitful. But the other reason that drives that administator's way of doing, is a mere spot question. Nicer advertisement picture, more clicks and visits to the group.

FlickrReferComment - a useful Greasemonkey plugin created by Pierre Andrews - automatically shows where the picture has been seen. And also with probing precision:

The "proof" is there, but where are those appealing little sticky pictures? My contribution to that code is my OurOwnSignature feature. It lets to automatically add a custom signature, right the one chosen by group administrators, when you come from a group stream. Everything automatically.

No need of any boring and time wasting "copy-and-pastings".
