In some browsers, you can click open a new window (or tab) without closing the old one by holding down "CTRL" while you left-click on the new link.
I always have several windows (or tabs) open when I'm searching the site for something, while answering a post. Or while adding details to a database entry.
I wish I could add multiple photos at the same time, via multiple-select, but usually each one would benefit from a different title, and some other data details might differ from photo to photo.
