Binaries, man, binaries. Otherwise, it'd be around 350k unzipped, including current images (24-bit PNGs, a few with alpha channels). AFAIK, I think I have to include a lot of text and images. When I tried to ask, I was mostly just told that the license was meant to be as easy to read as possible (some parts were obvious, but some not so).

For ad-supported sites, I'd not worry (is xcal unbanned yet?), but this place is both free and not ad-supported, and I don't know if the hosting is costing anything based on bandwidth, or if such bandwidth is a concern. If so, I could include instructions on installing IM, but that would seriously cut down on potential downloads (the size would already kill most anybody using 56k).
