mootjeuh has updates his Simple Image Viewer for the PlayStation Portable.

Changes:

Man, already a new update =P
I made this version a little more user-friendly.
Let’s say, if the image you want to display is bigger that 512 pixels (in width or in height), the program will only show a rectangle of the image up to 480×272 (the PSP’s screen).

I’ve also added an auto-centering feature, if the image that you’re trying to show has a reasonable size (lower than 480 in width, and lower than 272 in height), it will be automatically be displayed at the center of the screen =D

And there’s also intraFont support! But it has to be located on the memory stick, because, what good is an image viewer utility if it browse’s the flash?? =P
