Code:
u32 header[10];

SceUID fd = sceIoOpen(eboot, PS_O_RDONLY, 0);

if (fd >= 0)
{
    if (sceIoRead(fd, header, sizeof(header)) == sizeof(header))
    {
        sceIoLseek(fd, header[3], PSP_SEEK_SET);
    }
}


It will leave you at the PNG header. Change the index in header[3] for other data according to that document.
