I think I would create a new template for the autonav to do this. In you blocks folder, create a folder called autonav, and in there, create another folder called templates. Then, copy the view.php file from concrete/blocks/autonav into your new templates folder and rename it something like imagemenu.php.

You can then modify this template to display the menu using images instead of text. Then, when you insert an autonav block, you can click on it, select templates, and your new imagemenu template should appear in the drop down and convert it.

Shout if you get stuck!

Hey thanks for the quick reply, I have done all that, but I am clueless as how to edit where in the newly made php file to transfer from text to images,

Thanks again.
