Extend caption by Copyright

Hi all

Many thanks for this great module!
I have a node with a multiple image field and a (single) text field for the copyright information which is identical for all images in this node. I've created a view with the image-field and the colorbox formatter and combined this view with the views slideshow module to display the view in a block with one rotating thumbnail. this works all perfect and when I click on the thumbnail in the block, the colorbox opens as expected. :-)

BUT... I should integrate the content of the copyright-textfield in the colorbox, below the caption.
Is there any option in the views backend which I can choose or do I have to create kind of a template for this or am I missing something else?
Btw. I'm using the Stockholm Syndrome design - don't know if this information is important...

Many thanks in advance
Michèle
