I just installed 2.5 a few minutes ago hoping to upload my first album or gallery, but when I tried to upload images, I couldn't find the option to upload multiple images.
I tried clicking on the browse button and I could only select one file. No amount of Ctrl-clicking, Shift-clicking, clicking & dragging, or selecting with the keyboard would get me more than one file uploaded at a time.
One thing I noticed is that instead of showing the "Choose files to upload" button shown in the Screencast demonstrating galleries, my dialog still showed the old text box + "Browse" button + "Upload" button.
I'm pretty frustrated here - this was the one feature I was excited about in WP2.5 and I can't use it. Can anybody help me? Thanks!
