are there any apps that allow me to view a sertain format of pictures on the psp?

what i mean is that a few months ago i got my hands on an app that lets me view a sertain tipe of pictures format that the psp cant support and it also allowed me to listen to music while i read manga of my psp. but the problem is i have formated my pc so many times that i have for completely deleted this app.

if anybody has anytipe of good application that would allow me to view pictures on my psp (as dum as it sounds) i would realy apreciate it.

P.S. ITS NOT PORN JUST INCASE :rofl:

Well, irshell has a pretty good selection.
