There are also security problems: Images can be used to execute cookie stuffing and cross-site request forgery attacks; they use a lot of bandwidth; and they prevent bitcointalk.org's HTTPS from appearing totally "kosher" to browsers. These issues could be solved by hosting all images at bitcointalk.org, but this isn't worth the trouble.
