Images that are served from external links such as embedded photobucket images create a mixed content warning when viewed from a site that is served via https. The site content is delivered via https but the images themselves are served via http.
My internet connection is enough to serve a small private discussion forum but I don't have enough bandwidth to serve images so only external links are allowed. I would love to be able to serve all the content via https, even the external links. I understand it's not a big deal but it would be nice to be able to do it. The obvious easy solution would be to host all the content but again I can't...because bandwidth.
I did find a few references to image caching services but I'm not willing to pay for a service that isn't really necessary.
