sorting directory contents

I'm building a script that reads an image directory, outputting the name of the image, the dimensions of the image as well as it's size. It's using opendir() and readdir(), but readdir() doesn't return the directory back in any particular order. I'm not storing the results to an array because ultimately there could be thousands of images, and I'd like to save the memory overhead of building then sorting such a large array. So is there anyway to just read the results of an opendir() that is sorted by filename? Thanx! Joseph E. Sheble a.k.a.
