I have been using the global $pagenow variable to add instructions for users, but I need to somehow hook into the add image popup as I would like to instruct the users on optimal resolution for featured images.


  • If you are using a plugin for the popup then simply add the notice in the Pop-up's parent 'div' using html tags in the template file. This will help you achieve what you want. – WisdmLabs Sep 24 '14 at 10:41
  • Unfortunately I'm using the default WordPress media pop-up. – Karl Newark Sep 24 '14 at 11:45
  • Yes i understand that you want to add a notice in your default add media WordPress popup. If you are familiar actions and filters in WordPress then you can use this filter: media_upload_tabs – WisdmLabs Sep 25 '14 at 6:00
