Hi ramsey1971
To add link for an image, you need to put the image inside a 'Link block' add-on. Here are steps:
1) On editing mode >> Add-ons >> Basic >> Drap& drop 'LInk block' into column with image:
2) Now, you see a link box above the image, drap&drop image to this link box:
3) Hit the 'Link box' in the navigation, you will see the 'Href' field in the right panel and put your desired link there.
I just made a sample for the first image on your site, kindly check.
