Good morning and thank you for the Intro Theme… It’s awesome !!

I installed jetpack and configure everything as requested (I think, I’m a newbie) and I created my portfolios but unfortunately, on my website (installed locally for now) the featured image of my portfolios, it’s linked to the featured image and not to the content of my portfolio and I did not find how to change it.
How can I link my feature images to my portfolio in order to show a slide of several images ?

Thank you for your help.
