Generate thumbs by visiting a URL such as your.com/thumbs/images/image.50x50.jpg. This will create a 50x50px thumbnail of your.com/images/image.jpg.

The thumb will be stored on your server at your.com/thumbs/images/image.50x50.jpg so the next request for the same image will be loaded without loading php for ultra fast image cache.

I was building a site for a client and all imagecache stopped working before I uploaded to the live server.

When I uploaded, all of a sudden imagecache stopped working. I checked the usual things (permissions, original image exists) and everything was fine.
