I would like to add a caption on the featured image. The caption only appears if the image is inputted manually into the post. There have been other requests for this in the past (see link http://wordpress.org/support/topic/display-caption-with-the_post_thumbnail?replies=10). However, since I am not a programmer and know little about code I need some help to find out where this code would even go. I think this is an important feature becuase it has to do with copy right law. I do not want to post images that I cannot cite the source. So far I have not been able to publicize my cite becuase of this concern. Can anyone help with some information on what the code is and where I can input it into my template?
