Convert Picture slide from HTML & Javascript to a ASP version

I would appreciate if somebody knows how to change this application from HTML into a working example of ASPX.

It is taken from the schools website on html. I have modified code to show you what i want, by changing a series of img tags to a Datalist control for thumbnail image display. On image click i want to display same image but full size in another adjacent image control.Also,include count of images and the current image number as illustrated, with a description field present. As i understand it involves getting the dataindex as a count variable so that the paging links can find corresponding images and the current imageID to display.
