How can I change the title of the paintings, not the file name!

I understand how to change the file/photo name, but how do I change the title of entry A, B & C?  If you check our jotform entry form it has a place to put the title of painting A, B, and C.  That is all I want to change.  I DO NOT WANT TO CHANGE THE FILE NAME ON THE PHOTO!  I understand how to change the file name as I had to do it for someone already, but this is just the title of the painting and since the photos are already downloaded by the artist, why would I need to do this again?

The titles of the files can only be changed in the file itself.  It is not possible to edit the name or contents of a file after it is uploaded.
