How to compress external images? I load external feeds and i show thumbnails from external links.

I have big problem with Google PageInsight.



Images are not in my server, they are links from feeds. How can I compress those images from feed ?
Actually darol100 is right. Since images are not on your server you cannot compress them. But you are able to cache them localy with image cache.
