Just use normal HTML , eg:
<a href="URL"><img src="IMAGE" alt="FILENAME" /></a>
Thanks and what will be the path to the image?
Will using the path as I see it in firebug when I hover one of my theme thumbnails work?
Just go to your TF folio and select the image, view source, copy and paste, you’re done
In FF right click on your thumbnail and select “View Image” than copy your image path in address bar. That’s it
or just right click and select “Copy Image Location”
