after searching and reading the forum still didn't find a solution.
I have two kinds of posts - illustrated by images and by embedded videos.
There is no problem with having image thumbnail appear on the home page.
There is an option in Tubular theme to display video thumbnails as well.
Can we have both
images and videos thumbs on same page? Is it and how it is possible? (Creating a screenshot of a video as thumbnail is not an option I'm looking for)
Maybe not Agent, but other theme?
