error occured on folder with metadata (under picture library)

Question

I'm using MOSS 2007 Ent ed.
I have created a picture library for each dept under a site. For each departmental picture library, i have created few folders. Since I would like to have folder with event information (Event name, Event description, Event date), I used content mgmt to add in metadata into folder. I have no issue with upload the picture into folder and assign folder properties. The error occured when view picture from one to another folder. Does any one have idea on this? or can anyone share/advice on how to category picture library based on requirements above?
