I've uploaded all category images from the old site. When I go into a category in the virtuemart backend and view the "images" tab, the image is there and shows the correct path.
However, the images do not appear on the front end of the site and when saving a category in the backend virtuemart says:
vmError: Media files must have a title
How can I get the images to appear on the front end of the site?

I tried using the media sync tool. That didn't have any effect.
Turns out it's a RocketTheme Template issue:
