what is frustrating with this is that the option appears available, i.e. that for each image in the editor there is the option to “enter a URL” or click above buttons for presets. I keep entering the URL, which is a link to a WP page within my site, and the change never saves after I hit the update button. As I can achieve this by inserting images individually into the page, but not in a gallery, there must be a simple fix. Please please please can we have a fix for this? From looking at the forum, i’m not the only one looking to do this…
I am having exactly the same problem, trying to link thumbnails from the gallery to a page within the site rather than the image url. Driving me mad also. It sometimes works when the image is inserted into the page individually, but not in the gallery. there’s got to be a quick fix for this, seems very basic but a serious shortcoming.
