The camera does not require any extra software in XP to operate. As soon as you connect the camera to the USB port, Xp detects it as a digital camera and adds an icon in explorer, but it does not map the camera to a drive letter.

Hmmm, my experience with digital USB cameras is that they all map their image storage as a removeable drive when you link them to the PC. I suspect if you check Explorer or My Computer after hooking up the camera you'll see there's a drive letter mapped that represents the camera's image storage. Now, the particular camera you're using may have installed its own proprietary viewing software that it registers to be brought up when the camera is attached; and that software may well NOT support shell drag and drop (can you drag and drop images from it into an Explorer folder?). If that's the case and you can't get your users to skip the software and use the mapped drive in Explorer instead, there's not much to be done about it except complain to the software writers and ask them to add drag and drop. Or perhaps you could replace or supplement the registered viewer application with your own that references the camera's storage? That way the user wouldn't even have to bother with drag and drop; your app could serve as a direct interface onto the images.
