For you shutterbugs: I've rewritten the UI for uploading photos. In short, when you click the "Upload photos" button, the file dialog appears immediately. You can then select as many files you want (ctrl-click), and upload 'em all at once. Should remove some of the tedium from doing galleries...
Oh, and while I was at it, I fixed those weird issues where you would sometimes see images in the photo picker lists that had been deleted.
