Answer for Add content to portfolio page

Hi, I ‘d like to know the same thing. How to add more images/content in the project page – the page you access after clicking the button ‘learn more/read more’ in the modal window. Right now only the featured image appears automatically in the left column and the data/text appears on the right column. When I edit the post I want to be able to put more images in the post on the left side but keep the data/text in the right column (small column). Sorry for the hassle! :)) If you can give us just a bit of a hint, would be great. Thanks!
