That's not what I mean.
Any image that is in RGB and 1920 by 1200 is going to be about 6.6 megabytes uncompressed, it's just a function of the image size independent of resolution.
The Pixel Size and the type of image, I.E. RGB, Grey Scale, B/W determine the size of the file.
Windows own background image is 2.25 megabytes and is 1024 by 768 RGB Bmp .
To be RGB 256 k the image can't be bigger then 340 by 250 pixels uncompressed.
I think the 256 k thing must be a mistype or something.
I may have found part of the problem but I'm going to start a new post since this involves a whole new issue.
