Strange image link behaviour on site

I have a feeling this has to the do with the .css of posts vs pages but not 100%, hope you guys can help.

I have a text link and image link on a post, both pointing to a .PDF download. You can see the link target by looking at the page source or simply mousing over it. 3/4 of the way down the page – http://www.feedmeideas.com/barknfly/. The text links works, but when I click the image (which should link to the pdf) I get an image cannot be loaded error, grr!

Strange because I create a test page (instead of a post) and it works ok:

I have been trying to get support through the theme provider but I have no way to access their support portal because I need the license certificate which I do not have access to, to get it I need to wait on another support team which is 5-6 days currently. Hoping it’s an easy fix. Thanks in advance for any advice.
