The site is currently under development so not publicly viewable.

plugin with default settings: http://screencast.com/t/bZvbWBg1

I tried and copied the generated HTMl on the front end, can you spot anything? => http://pastebin.com/ZYEed97K

There’s a lot going on on my server, for example I use ngx_pagespeed, that might garble things up? Still not sure why that text breaks right into the thumbnail url, I think that is the only thing wrong with the output.

Any ideas or feedback on what to check?
