But does anyone know how to put a click through url behind this image... I know this is not possible with css, but I can't figure out where I can edit this?
There's not a way to edit or add links using CSS only, but what you can do a lot of times is grab on to a link already on the page and then make it big enough to cover the image.
I checked http://thursdaydinners.com/ just now and I see the logo is clickable. If you still need help with this, please reply back and mark this thread as 'not resolved.'
