> This seems to affect other desktop OSes. On Windows, if I drag a JPEG or PNG from Firefox to an image editor such as Photoshop Elements or Windows Paint, the receiving program shows a random-looking file name with a .bmp extension. This could be related to how Firefox populates the image onto the clipboard(?) -- i.e., bitmap data only, not the actual file? -- or it could be caused by a preference of Windows or the receiving program to paste/transfer the bitmap data rather than the file. (I have Windows set to show common file extensions, in case that makes any difference.

Windows does not allow dropping images on Taskbar buttons, which I guess would be the closest thing to the Mac OS dock.)_
