Project URL Issues

I’m using the free version but I have a problem with linking – I want the image to be clicked on to go through to a particular page. I’ve entered the following URL http://getindependentfinancialadvice.co.uk/24-areas-where-advice-can-make-a-difference/when-you-have-a-mix-of-pensions-from-different-past-occupations/ in the box “Enter Project URL” in the plugin. However on the Gallery page – http://getindependentfinancialadvice.co.uk/24-areas-where-advice-can-make-a-difference/ – I can’t click through and can’t see how to do it. Please could someone let me know? Is this a premium only feature or not possible at all? Thanks
