If you work on your library's website, this infographic on when to use different graphic formats might be useful. Tech things like this always interest me (if you're only a little interested, skip down to the What Should You Use section at the very bottom for the summary). (via)

    tl;dr version: jpg – never, gif – animated only, png – always when not animated.

    Also, gif is pronounced hard G as in Guh-if. The G stands for Graphic, so the G should pronounced the same way. The creator is incorrect in his pronunciation.

    @Chris: my rule of thumb is pretty much jpg for photos, png for everything else, and never use gif because I don’t often do animations. However, if Photoshop’s Save For Web tells me that jpg will be a smaller file size than png, then I go with that.

    And I’m with you on the gif pronunciation (in other words, not like the peanut butter), and was disappointed a few years ago when the format’s creator came out on the side of the peanut butter people. However this is the internet so I get to choose what to accept as truth – besides, I’d been saying it the hard-G way for fifteen years at that point, so I’m not going to change.

  4. Chris Says:

    JPG compression is so awful, I really hate ever using the format.

    And let’s not forget TIFF for archives.
