I'm using completely custom html and css code. This issue has nothing to do with the html at all. The problem is related to the php script that accesses the featured image when its in use.
This is the line in my html code for the image, and it uses the image variable that should call in the featured image.
<img class="Border_Solid_2" src="%image%" alt="Client Photo" width="50" height="50" />
I have seen numerous other people reporting this problem, especially over at the Spotted Koi customer forum. They are the makers of this plugin. Here's the link to there...
If anyone is able to determine how to modify the controlling php file for this, please let me know. It's most likely something simple. Unfortunately the makers of this plugin are not responding to any requests for help.
