it’s another project page.
So, while I was in Here is a Project Page…I clicked on the “add New Portfolio Item” above the place where I typed the title.
That gave me a new page to fill out…where I added my portfolio images in Select Portfolio Images…first putting in the sizey stuff, but then going back to delete them. Not sure if that matters or not.
I left Categories blank for a moment.
In Portfolio Type in General below, I put Portfolio Masonry Gallery Right
And now I set a featured image, assuming that when another portfolio page pulls the first link to this page it will pull the feature image.
