Hey @WorldAffairs, thanks for your feedback! We do currently have a feature that shows you which email campaigns an image has been used in. To find it, click on the image you are interested in and look towards the bottom of the popup window that appears. If it's been used in a campaign, you'll see a link that says something like "Used in 9 emails". If you click on that link, it will display the campaigns of which that image was used.
Is this similar to what you were hoping for?
