Wordpress banner image maker

I'll try not to turn this blog into a Wordpress blog (especially as it is on MT) but I will be blogging some of the tools, hints and pages related to Wordpress in the near future whilst I play with it.
A useful tool for creating a banner to go with the default kubrick scheme, is Red Alt - Kubrickr which takes an image from flickr and resizes and "corners" the picture ready to replace the default blue square.
Its a basic tool, but with a good choice of photos and colours the final result is pretty good.
