The original warning appears to refer to a redirect to viglink.com - presumably a redirect from the image hosting site. Viglink is an advertising company that likely the image hosting site is linking to to generate the ads on the page. Maybe there is a problem with viglink - I'd be a bit wary if I saw this.
Tony, I had noticed the same redirecting. I got curious and checked with Norton. Here is a screen shot of their report on viglink.com. It lists two threats (viruses).
