Database of thumbs images

I need a script for php5 like a database of thumbs (a gallery thumbs) with three levels: 1 - thumbs + description on main page with new insert pics 2 - thumbs + description (categorie) 3 - gallery + description for each thumb of 2nd level (album) (this could find on some free gallery scripts) More I need on main page header the numbering from A, B, C, up to X, Y, Z with links that lead to respective link description, search window and RSS. Main page have the lasts (new) thumbs-galleries template blank, I know css-html so I can do it, I need only the php script for admin area with MYSQL DB. You can use a free gallery script like "Plogger" to modify or adapt, or others free commercial scripts. Don't need rotator or slides, only a collection, easy to insert images, to turn into thumbs, can be found automatically on alphabetical order, links to categorie thumbs page, that links to respective galleries. Is important to easy insert images and descriptions. Can view an image of what it should look:
