I know this topic has been brought up here hundreds of times and I'm pretty sure I know the answer, but since it involves the purchase of a SSL cert, I thought I would verify my suspicision first.
I have a site that has a SSL cert attached to it. I have another site without a SSL cert that serves images to the first site. Consequentially, my users get the Mixed Content warning. Since I control both sites, if I were to get a SSL cert for the second site for the images, would that eliminate the error? My assumption is the warning would go away, but I would like the opinion of others that deal with it on a regular basis before I buy the 2nd cert.
A following question to the original, if my image server also serves up another website that does not require a SSL cert, is there any harm in attaching the cert even if most content won't use it? I'm assuming not, but thought it better to ask first.
