Okay, I can confirm that simple-ubuntu.png is the elephant wallpaper and that it is 2.6MB while the two others are around 350-500KB. It doesn't seem to compress so I assume this could save 2MB on the livecd as well, though I may be wrong.
Is there any reason the original JPG can't be used? Or could the original author export directly to PNG to prevent this lossless encoding of a lossy format?
