The tradeoff with that is that it prevents you from adding them directly from the photo-insert button when editing a page (at least for some users—I can't add any images with spaces in the name, and at least one other user needed help on this a week or two ago). This means that the file name has to be manually typed in. It will auto-complete eventually, but less tech-savvy editors generally won't know that typing [[file: and then the name will cause it to pop up. Since the spaces don't interfere with finding images once you use the search function in the editor, it seemed like the lesser of two evils to me.

I'm totally happy to adjust my file names if we as a wiki would prefer spaces as a general rule, I just wanted to hash out the pros and cons of both methods.
