Upload User's Name on Postcard Preview

[Art By Vicky]

On the postcard, does anyone know if there is a way to display the name of the user that uploaded the image?  This is my situation: I run an artist website where the artists upload images of their work.  I would like to display the title of the image and the artist's name under the image on the postcard.  I would also like to link the artist's name to their profile, so the receiver of the postcard can access the artist's profile on which I have all the artist's uploaded images displayed.

Also, I have added the Username to login, But visible with full name modification so that the image's user's first name and last name appear instead of their username.  So, I need to make this work as well.

I don't even know if this is possible, so if anyone can help with this, I'd really appreciate it.
Thanks!

Postcard is no create with firstname and lastname. Only user name.

Thanks Thunderstrike for responding so quickly.  That's okay, but is it the username of the person sending the postcard or the image's username?

In POSTCARDS_TABLE , sender and recipient name (user name) - 2 info include.
