How Do Preview Pictures Work? (1 post)

    Just a simple question, I'm currently developing my own theme and I was wondering how the preview pictures work that I see on other themes.

    Do the pictures get inserted into the beginning of the text area where you would write the blog post? If yes, how does the_excerpt know which one of the pictures (if there are more than 1 in the blog post) is the right one to take as the preview for The Loop? - Or is there a special place to enter the picture path JUST for the preview picture?

    I'd appreciate some pointers.
