Pardon me, Wes, but I’m not tech savvy in any way.
When I set up the Portfolio, I followed the instruction in the tutorial. I created a page and named it “Properties for Sale.” I posted a short introductory note and chose Portfolio in the lower right portion.
I have several posts under the category Properties for Sale and those are the posts that I included in my Portfolio/Properties for Sale page.
When I saved the settings, this is what appeared.
I did not upload any featured image as thumbnails; they just appeared as they are, as if randomly.
I want to change some thumbnail images but I don’t know how.
Thanks
