Thanks for sharing my work and spreading the word! Here are quick guide on what I'm okay with and what I'm not.
Do not post my drawings on Twitpic, Flickr, Yfrog, Tweetphoto, or your Facebook photo albums. Those are for posting your OWN images, not other people's. Their terms and conditions even say so.
Do not post more than eight (8) drawings in one blog post. If you need to post more to make a point (like 'Marc Johns draws too many logs!'), then please ask my permission first. If your readers need to see more, then send them over to my site.
Do post my drawings on your blog (Tumblr, Typepad, Wordpress, SquareSpace, Blogpsot, Posterous, Soup.io, etc.), or image sharing or social shopping site (Pinterest, Mlkshk, Imgfave, Ffffound, Svpply, Polyvore, etc.). ALWAYS make sure you include credit/my name (Marc Johns) and a link back to my website (www.marcjohns.com).
That's it! Thanks again.
