Too Many Channels

What happens if I try to open a Photoshop CS image with more than two dozen channels in Photoshop 7?

You'll get a warning message with the option of canceling the open operation or discarding the extra channels (see Figure 16.27). If you elect to continue, Photoshop 7 simply lops off channels from the bottom of the Channels palette, deleting them from the image.
