You can turn an image into a link. For example if you have three different photo albums, you can create 3 separate pages that have photos only relevant to that particular album.
Then on the main page, you can add one photo to show what the overall album photos will be like or are about. To turn that image into a link, select (single click) the image and click the link button in the properties editor on the right hand side.
Select browse for existing page or file and select the appropriate page, click ok.
After saving/publishing, when you click on the image, it should take you to the page you've linked it to.
I hope this info helps, please let me know if you need further assistance.
