I have a image field on profile content type. And when users try to save the content without uploading images I would like to show pop up confirmation message "Are you sure you want to save your profile without photos?" with "OK" button. And I need the content to be saved only after the users click the "OK" button.
I thought I could do this with Rules module however it look like there is no action for showing popup message with "OK" button of confirmation.
Is there any way to achieve this?
