The following results were obtained using Arbor Image Magick. This tutorial is for those who know how to load an image at Image Magick.
Click on the TRANSFORM tab. Select SPLICE.
SPLICE: Splits the original apart with all the other gravity positions EXCEPT Northwest. But I'll bet with the proper + and + you could split the image with Northwest, too.
WIDTH: Control the WIDTH of the split with the first set of numbers: ??x?? (any numbers, 0 works, too).
POSITION OF SPLIT: Position the split with the second set of numbers: +?+?.
GRAVITY:
Best to use "Center"
BACKGROUND COLOR: Putting a color in the background doesn't work for MSN TV.
Background stays white, so to color it, use Paint.
Original, a jpg, 300x50:
Parameters: 10x10
Gravity: Northwest
This put a 10-pixel border along the left and top only.
So I added the following to the result:
Parameter: 10x10+10+10
Gravity: Northwest
(black border added for visibility)
Start over with original:

Parameter: 20x0-80+0
Gravity: Center
Original size: 200x200
Parameter: 0x20+0-80
Gravity: Center
Original size: 200x200
Parameter: 10x20+5+10
Gravity: Center
