Got the message across, that's all that matters. BenYeeHua is famous for derailing threads, but he always has a good point.
He mentions it because it throws off the HTTPS security indicator in the browser (since http images are being served). I tried switching your URLs to https, but the hoster does not allow such (shame on them!). Every site should at the very least allow SSL, and preferably default to it (as Bitsum.com does).
