Mark -
A while back I went to Gallery and couldn't even figure out where to download the software! I sent on the site link onto a more computer literate friend of mine and he said he would try to use it, but there was some issue of security with using it on his business-backed site. I'm not sure what he meant, but it may be a consideration as to why someone may be better off to take you up on your offer.
As for Yahoo, I don't have a problem with it anymore, and the only thing I don't like about it is that it doesn't show the number of views and you have to be a member of Yahoo to blow up the pictures to full-size (weird?).
