I'm looking for a plugin that would add a field for uploading (or even better, selecting from the media library) an image that is "related" to the post. The purpose is to show the image next to the excerpt on the site front page. I don't want to necessarily show the image in the post body and the post body may contain images I don't want to show next to the excerpt.
I tried to seach the plugin database, but all I could find was gallery and Flickr plugins. I wouldn't like to take the time to code this myself if someone else has already done to work for me :-)
