Thanks for the tip! I'll try to find one. If nothing else I can just tape a filter from my SLR over the lens.
Your image confesses that you used a Kodak DC290 to take that pic. Kodak makes a threaded adapter (Item 867 5027) for this camera to take 37mm lenses.
Lens Adapter for KODAK DC260/265/290 Zoom Digital Cameras
A high-quality, molded slide-on adapter with twist-lock that allows these cameras to accept auxiliary 37mm screw mount lenses.
I'm pretty sure this link is safe here since SWF doenst deal in photo equipment....

Bad news is that it seems like its a discontinued product and appears to be impossible to find. I tried to find you a link but every place I went to said they were out of stock including photo.net's classified section.
Looks like the duct tape adapter is the way to go. Heh.
