A significan chunk of my website relies on imager / photography from external sources. I encountered a problem tho. Despite great support from css-trick community which helped me improve website speed quiet a lot, there is still one huge problem. External images are not caching ;/ I’m wondering if there is a method to do that? Looked into things like max can, but they only cache images that are on your server. I know one obvious solution is to actually store them on my server, but that would just chunk my bandwidth allowance down, so I’d rather deliver images via third party host like imgur.com
