At the bottom of my wordpress posts I want to have a main image and several thumbnails undeneath it. When I click the thumnbnails I want them to replace the main image. Is this possible? thanks.
So you just need an image gallery plug in? Try Next Gen Gallery. You can create multiple galleries with it. There is also a gallery feature already in Wordpress that will place a gallery in your post or pages...not sure about the layout and the "main" image thing.
Basically what I want is several images within the post, but only one displayed and the rest as thumbnails which will replace the main displayed one when clicked on. Is this possible?
