I've been working on implementing SSL for some time now, and it's all going fine. There's one issue I haven't been able to work around, and it's users embedding images/attachments. Is it possible to force all links to https? How does this forum solve this issue? Even this might be an issue as not all websites have a SSL certificate installed. The forum has lots of attachments, images and embeds, mostly from imgur. I do realize that even if some resources aren't encrypted, the other ones are and as long as it's not sensitive information it's OK.
