I guess my question wasn’t clear – I’ve set up the back-end – that seems to work just fine.
what I need is to create a custom template I guess and call it something like taxonomy-media_tag.php – the question now is what I need to put in there to show all the pictures/attachments with that specific tag – I’ve done it using the Genesis theme but I don’t know how to do it using GeneratePress?
Thank you in advance for your input.
