i tried to paste image from URL
[url]http://image.allmusic.com/00/amg/cov200/drc400/c457/c4573297y91.jpg[/url]
after this, 1pixel has been cutted from left and bottom sides of the image, and 1 pixel has been added both to the top and right side of the image.
then, i tried to save image to disc and load it from file - all was ok.
