It can be a pain if you do it with a GUI, but that's the kind of thing command line tools are made for. Assuming you have saved your 3200x480 image as full.png, converting it to 4 contiguous 800x480 JPEGs is as simple as

Code:
for x in 0 1 2 3; do pngtopnm full.png | pnmcut $[x*800] 0 800 480 | cjpeg > bg-$x.jpg ; done
with Netpbm, or even:

Code:
convert -crop 800x480 full.png bg.jpg
with ImageMagick.
