This should include miliseconds or a serial value (imagine trying to grab a bunch of shots of TNT going off hoping for a good one).

I'd also prefer if this used ISO 8601 format ("%FT%T" without miliseconds).

Well, the T is easy enough. I don't like the '-' in filenames but that should not stop them being used (we discussed this on IRC briefly) so %FT%F is ok with me. The ms or serial is the more problematic issue. Do you have any ideas? I suppose getRealTime() can be appended as well (or some division of... maybe %1000 for a 'serial number' in the range 0-999 (I doubt many computers will be able to take 999 screenshots a second)?

By "serial" I meant screanshot_foo.png, screenshot_foo-1.png, etc --- like the player saving code does. Dashes should not be an issue at all. In ISO 8601 format the miliseconds are appended seperated by a dot. It could be a colon instead if dumb file managers cause issues though. Milisecond resolution should be plenty, although something inside me prefers the serial version because you probably could take two screenshots in a millisecond and it should still work.
