This little darling will save you space by resizeing your picture to a much smaller scale and there you have it. Its perfect for those facebook photos that you just cant bring yourself to delete.
Just remember thats its gonna seriously lower your image quality if you go and shrink everything to a tenth of its size and try to enlarge it again to print, so dont be doing this for those wedding pics.
Hope it helps someone.
