Looking To Rewrite Image Urls From Merchant Datafeeds

I know this can be done but how?

[Chef_Brian]

I am looking for any clues on how to add code to my htaccess file that will rewrite image urls from datafeeds. I am working with popshops to pull in products from various affiliate programs via datafeeds.

Many of these feeds contains images that are stored on merchant sites. I would like the code of my site to read as if the images are hosted on my site versus me hotlinking to the images.

I know this can be done, one ebay wordpress plugin has two simple lines of code to add to htaccess to rewrite ebay images. However I can not seam to tweak the code to work for other merchants.

Any help would be appreciated.

Thanks,
Brian
