Hello, I just upgraded from 2.0.6 to 2.1. There are at least 2 issues with images that I've found.
1. I insert images into a post by clicking the thumbnail and dragging to the post (since there is no "thumbnail" option availably on the right side when you'd click the "Send to Editor" button). OK, the thumbnail is inserted beautifully. Then I go to the blog and view the post. The thumbnail is there! Yeah! Then, I click the image to view a larger version and there is NO POPUP. Instead, it goes to the Admin login page. If I am already logged in, it goes to the Images dialog in the "Browse All" setting in the Admin interface that is within the Post interface; however, without the rest of the interface.
2. I've tested every single lightbox plugin possible on the web, and they all break - my guess, though, is that it is because of issue #1 (the link is not correct).
Thanks!
Scott
