I'm pretty sure that refers to images that continually rotate, not just on pageloads, and specifically that it refers to ads - I doubt my banner rotate would even register with them; it doesn't use any more bandwidth than just loading a normal image would. (Mind you, that paragraph also bans subhosting, so I wouldn't have borrowed space there anyway, and mp3s, and mpgs, and image archives...) I have a feeling that everything in that paragraph is only if you're doing that one thing only and egregiously and to such and extent that it eats up all your resources, but I could be wrong. How does it compare to other hosts' TOSs on those subjects?
