Hi nedash,
Here i have created a sample as per your requirement. So you need to change the desigh as per your requirement and you need to follow the below steps to implement in your code.
Step 1: The main thing is when binding from database you have to assign the image url to href of anchor tag and src/ImageUrl to image tag.
Step 2: Assign attribute as rel to anchor tag with a groupname as i have the group name as group1 in the sample.
Step 3: In document ready function you have to remove the attribute rel from anchor tag if the image src is empty.
Below is the working sample.
