I am using Zenphoto on my website and using the Default Dark theme to showcase my portfolio. I am a bit skeptical about showing full size images of my work. Is there a way where I can limit the images to appear only in thumbnails and disable the clicking for larger images completely? Please reply.

In the theme folder for default dark there is a file called image.php

go down to your image div and remove
">

and replace with
``

This removes the link to the full sized image

Thanks for this Chilifrei. It worked like magic
