Hello
Thank you so much. I got it to work
In the media library I first copy the URL of the image which is displayed on the right hand side of the screen, then I go back to the page and click on the image so the toolbox appears. I click edit then in the display settings I click “Link to custom URL” I then paste the link into it and click Update, and it works. Now when I click on the image a bigger version pops out. The two plugins I have activated are Fancy Lightbox and Lightbox slider. Not sure if that makes a difference but I’ve got the solution I wanted. Thanks ??
