I have used a zip file to load 350 images into the gallery.  How do you create the xml file to update the title, description and scores?  There isn't even a text box to modify the score when you click edit image.  Does this module use a database file to update the xml file (I couldn't find one).  Are there any other modules that will work similarly if this one can't do bulk updates?

What I am trying to do is post company logos and have their company name and description displayed.

You could upload bulk files, and then edit all description after upload. The bulk upload descript all files with the same as you dscript for the upload. BUlk upload can be done as zip file.
