First of all, I am new in psp coding.

Second, what I am trying to do is to write a small program that can view jpg files stored in memory stick (my DC uses memory stick too). I want to view the photos i just take via the big big psp LCD screen instead of the small small one in my dc). The psp can only view image files stored in specific folder, and it is very slow when a big image, say 3000*2000 and 4MB, is presented.

I tried to learn SDL for my small program because of its simplicity. Owing to the limited ram size of psp, directly loading big image file will lead psp into a crash by using IMG_LoadJPG_RW().

So, is there any way to load just a part of the whole jpg file into SDL_Surface ? Then I can deal with the small part in psp.
