What do you
mean, "within the image"?
Discussing the matter withing the image
description. The problem would be the missing documentation when the picture is deleted.
I would prefer to discuss on the talk page, it should be separated so
that if the result is 'keep' the debate is still around without diving
into the history.
What about simple daily pages like we use at
http://de.wikipedia.org/wiki/WP:LKB?
There's nothing inherently wrong with that approach... except there
are currently 48 days listed on [[COM:DEL]].... instead of the 7-10
you might expect. I don't know that making those ancient debates (back
to June 25, what is that, 7 weeks?) less visible is going to make them
more likely to be resolved.
