But you would have to store the URL as well.
I would think a text field for the URL would be needed and your containter field should be set up to act as a button. The button action would be "Open URL"
And in the Open URL options the URL to go to can be specified to be the URL field.
Hmmm, might be able to add a web viewer to your layout to display the image and then use button set up to make it a button to do the Open URL...
