On Special:CX clicking an image in the target column opens the image description page.
It's not necessarily wrong for the image to work as a link to its description page, but such behavior is non-intuitive and destructive, because the page is not auto-saved.
A different behavior must be defined for images in the target column. Some possibilities:
- Clicking does nothing (but when publishing the page, we must care to make it work correctly as an image)
- The image works as a link, but opens in a new window or tab.
- The image opens some kind of an image properties dialog (this should only be done if we are doing something specific for CX; otherwise it should be handled by VE)
