I really like the built in gallery option in 2.5. I have noticed one issue though. Well...two, but this post is about one specifically. When viewing a single image (the subpost) in an image gallery, the permalink adds "attachment" to the url, sort of like this: hello.com/gallery/2008/04/attachment/dsc-1234/. This apparently only happens if you have the category in the permalink structure. That is when I remove /%category%/, "attachment" also disappears. Is this a feature or a bug? Is there anyway I can have the "attachment" removed from the permalink without removing the category?
