PNG's main strength is for transparency. GIF offers transparency as well, but it pixelates the edge of transparent images, especially drop shadows. PNG has the ability to sustain soft edges/gradients on transparent images, but it has a larger file size. There are websites like tinypng.com that remove a lot of back-end data and maintain quality if you ever need a smaller file size PNG. Also, PNG is only used for web, because you can't have a CMYK png for print.
JPG's main strength is having a good balance of resolution and file size. It's used for both print and web, although TIF is preferred for print to maintain the highest quality image.
JPG produces the easiest route for d2jsp sigs, but GIF is for animation and/or transparency, and PNG is for transparency with soft edges, but you have to reduce the file size with third-party programs to meet d2jsp regulations.

this is actually a great question..
i notice alot of the time its better to use .jpg for animation and user input.
png doesnt preserve any transpare, png is great for large unscalable pictures
good topic.
To clarify this troll comment for the OP, GIF is for animation. I think you might be confused by imgur thinks with altered URLs that show the JPG extension.

nah man, all wrong.
jpg is great for animation. hands down. png doesnt do transparency, it just tricks the eye. devil extensions
To clarify this troll comment for the OP, that's literally its main, distinguishing feature. You might not have a checkbox checked.
