Script needed to scroll images from right to left

Hi, I need a script that will scroll (marquee) ads from right to left or left to right. I have the image links stored in a DB (the name and location of the image) I call the images and display them in a row, the images are a mix of JPG's Gif's and Flash animations. I need them to scroll slowly in a continuous loop smoothly (no flashing of stuttering issues) if you can do this or have a script that does this let me know how much it will be. If you can please show me a demo of what you have... Thanks Yankee
