I have a plug-in that allows for repeatable fields. There will be an image and the image description. The description allows for tinyMCE editing. There are obviously problems with this, but I think I have found a solution.
What I am trying to do is save the metadata after the user closes the thickbox and the image filed is populated. I'm wondering if there is an 'add_action' hook that I can use to accomplish this. Any ideas?
