Heyhoe

Is there really any reason people still need to be shown the file name prominently with extension and everything?
It's really the only part of the lightbox I dislike. Mostly due to the fact people tend not to cleanly name photos in the galleries I visit, so it's just a long string of stuff (usually generated off facebook or some other tool which seemingly auto generates a name). I don't see a problem in showing it somewhere, but it just gets so much (and in my humble but totally subjective opinion, over weighted) prominence in that top left position. From a UX/UI perspective, I actually don't think file names have much relevance at all now that you've got drag and drop working for image ordering - there is very little (if any) additional info conveyed by the file name.
I'd prefer (speaking as a consumer of galleries) that the caption stay blank unless a user completes it vs filling it with the filename.
