Images loaded from another site

Hi,

I’m in the process of importing listings that have a lot of images associated. However, instead of uploading each image to my web server, I would like to have the client browser load the image directly from another site. When I use the external URL for images in the import IMAGE fields, it strips off the external domain and looks locally for the images. Would there be a way to override this behaviour and allow GD to handle the external image references in such a way as the site functions the way it does today, only with the images loading from another site? We have permission to load the images from their original source site, and it would save a ton of time, effort, and transfer.

I expect I could add custom URL fields for these, and create my own templating/output for them. But I would much rather utilize the already handled image stuff in Supreme template and have it function transparently (some listings might have local images, some might have external images, etc).

Thank you
