I am creating a gallery of images and found some code that sorta works for my needs. I am using CSS and Javascript. My thumbnails are listed in <LI> tags and when clicked on javascript is to change the full sized image and changes the css on the clicked image to let the user know which thumbnail is selected.

I split the <ul> between two div tags to take advantage of background-image capabilities. I have one image for the thumb and another for the full size (i.e. -- image1_tn.jpg and image1_fs.jpg).

How would I modify the following code to get the full size image (in a folder titled 'fs') to replace when the thumbnail (in a folder titled 'tn')?

Thanks!

Hello Aus2Srq,

I am not sure I understand how the layout is to look, but perhaps this will work (or at least be a good start)...

I hope this helps!
