I already have a Featured Image picker on my Wordpress that chooses the image to be shown on the front page of my site. BUT, I want another image picker just like the featured image picker because I would like the authors to easily choose a image that should be shown at the top of the article.
The reason for this is that I want to show an ad after the title, excerpt and a second image. And this second image needs to be chosen somehow, and the best way is to do it the same way as a featured image.
But, I dont know where to begin with creatin such an "widget" for the "New post"-editor.
I know both HTML, CSS og PHP, so the programming aint a barrier, I just dont know where to start.
Best regards, Markus
