Cannot remove hyperlink from image
For some reason InDesign has no option to remove hyperlink from an image. It took me hours to search for solution until I gave up and deleted the image and recreated it with a new hyperlink. This is pathetic and needs to change. When you right click an image, we should see "Hyperlink" > "Remove Link". This is so basic, its really upsetting to have to post this here.
Did you try clicking on the Trash can icon in the Hyperlinks panel?
