We've used this plugin for 6 months now and Google Chrome has flagged our website. After investigating the source code we found that the script calls a a site rod.gs (url shortener but was flagged for distributing malware) we simply switched to another plugin, Grand FiaGallery. We get this message when using this plugin:
http://www.cosy-comfort.com contains content from rod.gs, a site known to distribute malware. Your computer might catch a virus if you visit this site.
Google has found malicious software may be installed onto your computer if you proceed. If you've visited this site in the past or you trust this site, it's possible that it has just recently been compromised by a hacker. You should not proceed, and perhaps try again tomorrow or go somewhere else.
We have already notified rod.gs that we found malware on the site. For more about the problems found on rod.gs, visit the GoogleSafe Browsing diagnostic page.
