AA88 on "Albums and Sub Albums"

Is there a way to have sub albums be listed in a parent album and only display parent albums on the main page until the user clicks the parent album they want to view? Then the sub albums will display on the other page which is linked to that parent album and when the user selects one of the sub albums it goes to projects page .
I created all the pages and it's all static design,I created a page called Projects.php,subalbum1_1.php and album1.php, and just linked them,but the problem is when I add a new category I have to make a new php page and I have to do that even for the sub albums because every album and sub album includes their posts. but is there an automatic way to do that? i read other topics related to this and they recommend plugins to use, can I do that without using plugins?
tnx
