I've upgraded to 2.5 this morning and I am mostly very happy.
I've noticed the new media library and I find it great. I would like to import 360 images into it (from my previous blog posts). I've created the appropriate directory structure i.e. wp-content/uploads/year/month/filename and copied the 360 images but I can't access them from the Add Media window.
Any idea what I should do next to make WordPress become aware of the images?
