Display Post Contents Dynamically

Hi

I’m trying to pull content from posts in one category and display the title, content and attached images into separate divs in a custom page theme. I need to be able to toggle through the various posts’ contents by clicking on their thumbnails.

I can grab the posts with get_posts() and store their data as arrays, but I can’t find any way to dynamically change which post’s content is displayed in the page divs when the thumbnail is clicked.

Is there a way to do this with permalinks or anything else?

Thanks!
