I agree with compression whenever possible - it's great for wiki backgrounds, wordmarks and other omnipresent elements (see where I nearly halved the MLP wiki background JPEG in size). Though I wouldn't make it mandatory, as some users may not be tech savvy enough to do it. I used online service JPEGmini for my JPEGs, and computer application PNGGauntlet for my PNGs.
