Just added a new feature at Cogteeth¹: the Cogteeth Bookmarklet. Once installed, this allows you to create a Zazzle product from any image on the web.

Probably half the development time on this was spent getting it to work with Internet Explorer. In the end I had to produce a slightly different version specifically for IE which may not look so pretty when used on some sites. But of course there's an easy solution to this - switch to a decent browser.
