@Koleax: Seem like the compression level is about 85% (100% = no compression).
I think it was done that way so that you could send taken images via an PM over
the PSN, which had a 1MB size limitation for an attachement. The current limit
is about 4MB. Personally, I wanna have an 1:1 framebuffer grab.

Another cool thing would be if we were able to assign a button as a snapshot
button to quickly take images during a race without interrupting it. Pretty cool
for online races! It wouldn't take much to implement it, but it might
be a bit more difficult to prevent the game from shuttering during the grab.

@kaori: The compression level of your images do hurt my eyes.
