I'm using Headway themes. I deactivated every other plugin but the gallery thumbnails only show a very small 10px X 25px or so vertical rectangle. If I right-click in Firefox to view the thumbnail image, I get this error message:
A TimThumb error has occured
The following error(s) occured:
Could not find the internal image you specified.
