Here is the subclass I use to get this information. And I agree, it
should be accessible. I've filed a bug report and I'd suggest you do,
too.

@implementation RTImageView
/*"
   RTImageView is a subclass of NSImageView that will send out a
   notification when an image file is dropped on view. The notification
   will include the path to the file in the userInfo dict under the
   key @"File".
"*/
- (BOOL)performDragOperation:(id <NSDraggingInfo>)sender {
   BOOL val = [super performDragOperation: sender];
   if (val) {
       NSPasteboard *pboard = [sender draggingPasteboard];
       NSString *plist = [pboard stringForType:
NSFilenamesPboardType];
       if (plist) {

           NSArray *files = [NSPropertyListSerialization
propertyListFromData:
               [plist dataUsingEncoding: NSUTF8StringEncoding]
               mutabilityOption:
NSPropertyListImmutable format: nil errorDescription: nil];
           if ([files count] == 1)
               [[NSNotificationCenter defaultCenter]
postNotificationName: RTImageDroppedNotification
                   object: self userInfo:
[NSDictionary dictionaryWithObject: [files objectAtIndex: 0]
                       forKey: @"File"]];
       }
   }
   return val;
}

@end
