How to insert code (image copyright) after article image?

Could you please help to find the way how can I insert some code (link to image or copyright info) just after the image of the article (news) on the main page? I can do it inside the article but how to put it on the news page?
I have attached sample image to show where I want my data be inserted.

Thanks in advance,
