I would like to use AJAX on my PHP site to simplify navigation and provide a more visual feature. In this task, you will not create any graphics or new database fields ?. Instead, you will change one text table, to a display of thumbnails. The data and thumbnails already exist in the database. The table, as it exists now, has 30 lines of product names, followed by Page: 1 :: 2 :: 3 :: 4, etc navigation. I want to change that to 20 thumbnails, followed by the same navigation style as before. Of course, the product name is listed below each thumbnail, and is linked to the product page. The reason I am doing this is just to provide navigation without having to wait for pages to load. I would like the navigation to be uninterrupted, that is, only the section containing the thumbnails will change when corresponding page numbers are clicked.
