I just made a dynamic menu that loads everything in from an XML file and makes a grid outta the thumbs.
[che che check it]
All you have to do is change some variables and you can change how many columns you want, where you want the grid to show up, how much space is in between each thumbnail and so forth. All you have to do to update it is open up the XML file and change the info to your own. You also have to put your own images in the images and thumbs folders.
