We have a images that are running long in the tooth and we would like to "retire" them and replace them on landing pages. What's the best way of doing this without going into each landing page/program and replacing manually?
I could only think of:
The first method you described would be the easiest for you. If you don't plan on using these images again, then it wouldn't matter if they're replaced by the new ones. You could also download these images from your pages and store them somewhere else in case you ever needed them again.
