I'm using Microsoft Pro Photo Tools to manage my meta data and Picasa to manage my photos. The problem is when I publish the pictures, the meta data gets appended with a question mark at the end.

Example:
http://gallery.testtubedummy.com/2008/2nd-annual-schematic-dodger-night/

Click on any of the image to see that the title, description and keyword meta data has a question mark at the end of each meta data.

Is there a quick fix or a hack to remedy this problem at this moment?

Sorry, not that I know. Our chief developer is out of town for a few day and since we have already a ticket there is being taken care of this.
