Hi Ciaran,
I'm using your great extension J51_GridGallery and I am really happy with it. Unfortunately there is no administration setting to change the position of the caption title. Maybe you could add this for a future version.
But for now it would be enough if you could help me getting the caption title "out of the box". This means I want to have the caption title below the picture centered.
Hope you can help me, as my trys weren't successful
Best regards,
Daniel
