That is, you don't need my permission to post these images on your website (and hotlinking with <img> is fine); just include a link back to this page. You can use them freely (with some kind of link) in not-for-profit publications, and I'm also okay with people reprinting occasional images (with clear attribution) in publications like books, blogs, newsletters, and presentations. If you're not sure whether your use is noncommercial, feel free to ask (if you're not sure, it's probably okay).
