Hi All,

I am trying to delete some photos from one of our product pages in Umbraco.  However, when I publish the page after deleting the photos, I receive a notice about an "unhandled exception".  Please see text below.

Item has already been added. Key in dictionary: 'rel'  Key being added: 'rel'

 Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Item has already been added. Key in dictionary: 'rel'  Key being added: 'rel'

Source Error:

Stack Trace:

 I have tried fixing this on my own and to find a technical support person, but to no avail.  If anyone can help me with this, please write me your advice.  Much thanks!
