I would like something very very simple. in php and mysql that from admin allows me to add categories and within categories game name, thumbnails "browse and upload" well something like this [login to view URL] Title and thumbnail to be linkable..with numbers on top and bottom for more games... and categories showing on TOP of each game page.. "remember thumbnails should be uploaded via browser to my server" So if you can do it fast.. jump to it..
