Joshua Eichorn has a reminder about the WebThumb (a PHP-based website thumbnailing service) contest that he's having.

The WebThumb contest ends on the 15th. I know there are couple projects out there that haven't officially entered. If you want to have a chance to win an upgraded Webthumb account make sure to get your entries in, the contest website has all the details.

The WebThumb service is a web service that allows remote users to request a thumbnail of a site and, when it's ready, automatically fetch it to be used however they want. You can even defined custom heights and widths for the browser to use.
