how i can resize by using it ? 5-8 MB uncompressed JPGE ..
Like I also suggested - and you resized (a bit). You can also resize the resolution. I can imagine that these image files have some thousands of pixels side wise. Note that SU won't display better resolution than 1024 pixels (or 2048 pixels if "Use large texture" is set in preferences) anyway so any image bigger than that is useless but taxing your system.
