In my featured images I have given credit to the copyright owner but I would like this info, including the description of the image, to be available as they mouse over it. I cannot get it to work in the "set featured image" function. I have used the alt text and title text and it is still does not show up when you mouse over the featured image.
The theme I am using is Expound. My blog is set to private because it is under major construction at the moment so you won't be able to see it, but I'm sure you understand my query.
The blog I need help with is discoverkamit.wordpress.com.
