Simple HTML Thumbnail scroll on next arrow gallery lightbox

NO FLASH. I pretty much did all i could. Here is my work so far. [login to view URL] You will be working on my image preview gallery located under "what's new." As you can see, there are 6 images with arrow on the left and right of the gallery. your project will be to make the arrows actually function so that when they click on the right arrow, the images scroll to the left to reveal new images. The Left arrow will work the same way. I want to add constantly new items so that people can see what new products are for sale. On click, lightbox image pops up with image title on the bottom and link to product on my store. I need everything to appear and function as it currently is, with the addition of functionality on the arrows. Again, no flash. Anything is ok as long as it works on apple mobile devices.
