If you would like to have the graphics available in good quality,
use PNG and it's lossless compression. JPEG has lossy compression
so that you'll get artefacts inside the resulting picture, zooming
isn't nice as well. JPEG is good for pictures like photos, PNG is
for regular graphics like screenshots as well. You may want to
make some tests before you decide which format to use.
