Use Image Styles with remote images? I have a set of images on a separate host, images are available by a URL. I would like to render one of these using Drupal's image styles, but I note that theme_image_style says it won't work with remote images.

Is this possible some other way?

I would like it to use Drupal's caching (so it doesn't fetch the original image every time).
There's a module for that.
