Portfolio images question

HI! I am working on my portfolio and have passed all the tests. I am currently working on styling it and am trying to add the pictures for my projects. I don’t know how to do that though. I have added the element, but I don’t know how to add the pictures (src) of my projects so they look like the example. Can anyone offer any advice?
