It does make sense.
Regardless of the legalities of it, it just seems 'right' that stuff which is openly on view on AW, would be OK to openly have on view on here (seeing as UKP contributes much of AW's traffic and also facilitates WGs generating custom).
But Private Galleries have to be paid for on AW, so posting images here circumvents that. The fact that UKP is a publicly viewable forum is of relevance.
And for AW verification photos which are purposely hidden by a WG for her personal discretion, to have them viewable on here doesn't seem right?
I think a good call by Head1 (and in any case its his website, so tough shit if you don't like it
).
