0104 "`Joint Photographic Experts Group <https://en.wikipedia.org/wiki/JPEG>`_ is "

0108 "can vary the amount of compression. This allows you to choose between lower "
0109 "compression and higher image quality or greater compression and poorer "
0110 "quality. The only reason to choose higher compression is because it creates "
