Unless it's a JPEG 2000 (which isn't web-safe) then it's lossy, even at
100% quality. The nature of the algorithm is such that there is always
loss involved, which is why it's best to work on photos that are not in
JPEG format, as each save and re-open creates more and more distortion
(although not much that will be noticed in a photo!)
