but it isn't
Here is the file size

Here is the Error

Here it is in Gimp

Does anyone know why this might be?
and btw the picture is of Mass Effect and the lame effect of darkening around the edges

I think this issue only affects Bitmap files of a very big filesize, but I honestly can't say why... i can see the resolution of the image is quite big as well, I have a few bitmap files 1600x1200 with over 5MB in size, but they are displayed correctly. maybe it has something to do with the resolution...
