clickable background image

Hi there,

you can't apply a link to a background image. But its possible to add a link to the container that has the background image.
If you're using GenerateBlocks Pro - it adds a link function to its Container Block.

Where can I read about it?

If you are using GenerateBlocks pro, here's the introduction of the feature:
