Hi Bart @maarschalk
Currently from the built in Options this is not possible, but with Some Custom CSS it is if you are willing to give it a go.
Here i have two other threads where i outlined similar ideas:
however in your Gridder, you will be setting a custom class or ID to the image, and then a custom class or ID to a text element, to link them. There are definitely more beautiful/elegant ways to achieve this, but if you like it give it a go :)
Good Luck and best wishes! thanks for using Lay Theme!
