Problem is that you need to have the actual photon counts. NASA (for Kepler at least) uses FITS files to store essentially a 2d array of photon counts. So converting to another format is not actually helpful.
But I agree that if someone is using it as an _image_ format they should reconsider their life decisions.

Sure, but for generating a quick thumbnail, it works just fine.
ImageMagick supports FITS, and will happily convert it to PNG or some other rational format. (It will make FITS files too, if you're feeling masochistic.)
