Sort by each letter/listing

I was wondering if someone could help me out with a script. I would like to have all 26 letters of the alphabet listed so that when a viewer clicks on the letter “A” i can have images show up that they can click on and be taken to an external link. I know I could do this manually, but I am going to have about 5-6 sections with each having its own list of 26 letters. An example of what im looking to do can be found at the link below

Ive been searching for 5 days now, ive read on paging, but i cant get the images to be included.

PLEASE PLEASE HELP!
