I am planning to build a portfolio using custom post types, so the main portfolio page will show a "featured" image for each portfolio post. Once you click on one of these images you will go to the actual post page for that portfolio item.
Once on this page I would like to show multiple images for this particular portfolio post. So I am thinking of doing some sort of slideshow or possibly a big image with little thumbnail images that when clicked will load the larger version of the image into the big image slot.
So I am curious, when making a post for a portfolio item, how would I go about uploading and integrating multiple images for each item?
See the bottom of my mockup below, when you click on a thumbnail for a particular portfolio item, it will load a larger image
