Hi, I was actually looking for something similar for some photos I plan to put on my site in the near future. I found some links but thought that I would check this forum first in case there were any better solutions, whilst doing that I happened to stumble across your post. I know it’s rather old but I may as well pop some links in that I have found. I found one to actually go into your WordPress blog (I know you weren’t particularly interested in one like that but still) http://www.fahlstad.se/wp-plugins/fgallery/ . Also, I am not sure how it works but I have seen a fair few people use – http://www.flickr.com/ , it seems decently popular although I have never used it myself…
Just to add when I was looking through this forum the majority of galleries appear to be widgets… Anyway hope this has perhaps helped if you still haven’t got a solution.

I see plenty of photo plugins, but none of the widget based plugins I see work independently of other sites such as Flickr. If you happen to come across one, please let us know Aidan. Thanks.
