Hi
I have Adobe Photoshop.
It show exactly how big the uncompressed size of the image is in Pixel Dimension, File Size, Inches, and the Resolution all at the same time so getting it under 250 k isn't the problem.
I just didn't believe it because it seems to also say that it supports images up to 1920 by 1200 in the list of supported file sizes.
However I now see that the list is of supported file names, not sizes.
Which leaves one wondering why you would want to name a file "background1360x768.jpg" if that isn't the size of it?

""As this is an OEM feature images are derived from %windir%\system32\oobe\info\backgrounds. Like the registry value, this folder may not exist by default. The following files (sorted by width-to-height ratio) are supported in this folder:"
backgroundDefault.jpg
background768x1280.jpg (0.6)
background900x1440.jpg (0.625)
background960x1280.jpg (0.75)
background1024x1280.jpg (0.8)
background1280x1024.jpg (1.25)
background1024x768.jpg (1.33-)
background1280x960.jpg (1.33-)
background1600x1200.jpg (1.33-)
background1440x900.jpg (1.6)
background1920x1200.jpg (1.6)
background1280x768.jpg (1.66-)
background1360x768.jpg (1.770833-)""

Anyway it does work if the image is small enough.
Windows own background file is 2.25 megabytes in size, so it doesn't have to live by the same restrictions.
