Populate image URL input box from another tab

Hi, I am writing a plugin that adds additional tabs to the add media window and queries a media library – this is all working fine.

However, I would like to somehow create a link so that when an image is clicked the “From URL” tab is shown and the URL (id src) input box has the absolute location of the image which was clicked.

It would be nice to do this via an URL as the only information I need to parse is the image location. Is there some sort of hook I can pass in the URL as a get value or something existing I can use to do this?

Thanks for your help.
