Sure, it's still a special interest if you just like looking at pictures. When I was one year old, one of my very first special interests was Winnie the Pooh. We were going on a long car trip to see my grandparents far up north, and my mom and aunt bought a Winnie the Pooh coloring book to occupy me during the ride. I'm told that I spent that whole trip either sleeping soundly or just staring at the pictures of all the Pooh characters.
Even as an adult, I still love just looking at pictures of the animated movie and TV characters I love. I have bunches of screencaps and works of fanart saved to my laptop.
