Back to WordPress 2.9, people are thrilling about a new feature called “Post Thumbnails”, I was one of them. Before it was a core feature, it was already a requirement for any premium theme in the market. Without doubt, add “thumbnail” to theme support was definitely a big moment in WordPress history. Later with WordPress 3.0, the name was changed from “Post Thumbnails” to “Featured Image”.
I love this feature from day one. I quickly add it to themes in clients’ projects, and they are as happy as I expected. After the name changed to “Featured Image”, things became a little different. Clients were still happy about the UI, I just got asked about the same question more often.
