Does anyone know how to SPLIT or DICE an image in Euphoria?

I'm looking at splitting .bmp (first), .png (second), .gif (fourth), .jpg
(fourth) images.

For instance, let's say the image to split into smaller images is 800 x 600
pixels:

(0,0) - - - (160,0) - - - (320,0) - - - (480,0) - - - (640,0) - - - (800,0)
  |            |             |             |             |             |
  | image 0 0  | image 1 0   | image 2 0   | image 3 0   | image 4 0   |
  |            |             |             |             |             |
(0,150) - - (160,150) - - (320,150) - - (480,150) - - (640,150) - - (800,150)
  |            |             |             |             |             |
  | image 0 1  | image 1 1   | image 2 1   | image 3 1   | image 4 1   |
  |            |             |             |             |             |
(0,300) - - (160,300) - - (320,300) - - (480,300) - - (640,300) - - (800,300)
  |            |             |             |             |             |
  | image 0 2  | image 1 2   | image 2 2   | image 3 2   | image 4 2   |
  |            |             |             |             |             |
(0,450) - - (160,450) - - (320,450) - - (480,450) - - (640,450) - - (800,450)
  |            |             |             |             |             |
  | image 0 3  | image 1 3   | image 2 3   | image 3 3   | image 4 3   |
  |            |             |             |             |             |
(0,600) - - (160,600) - - (320,600) - - (480,600) - - (640,600) - - (800,600)

There are some 3rd party Linux and Windows apps out there, as well as Photoshop
and Gimp, but I would rather have something to use in a Euphoria cgi program to
create web pages on the fly. That means that the app should be non-Windows (i.e.,
no Windows APIs, DLLs, etc.).

If anyone could point me in the right direction I would be grateful (and of
course, share the code).

thanks,
