Load First Item in List Onload

Load First Item in List Onload

My query skills are moderate and rusty. I put together a a page that is designed to show a linkable image each time a list item is clicked. The problem is, the code I found to do so only allows one image to sow at a time. Currently, all images are hidden on load but I need the first image from each list to show upon loading.

Can Someone help?
