Here's the code I used. It differs from what bplus had in that instead of trying to show specific images, I am simply cycling through a sequence of frames to show an animation.
It was a bit less painful than I thought it would be, although it certainly helps when all your images are the same width and height.
Some spritesheets optimize space by trimming them even further, which makes a mess of your width/height dimensions. To take it a step further, some spritesheets even simplify your sprites to polygons. Thankfully I don't need that degree of optimization, sounds like diminishing returns and a mathematical headache.

Code: (Select All)

CLS
SCREEN _NEWIMAGE(1000, 1000, 32)

DIM SHARED deathss AS LONG
DIM SHARED r AS INTEGER
DIM SHARED c AS INTEGER
deathss = _LOADIMAGE("SCRAPSHIP\x\gfx\death\deathSS.png")
_SOURCE deathss
_SOURCE 0
r = 0  'row
c = 0 ' column

DO WHILE c < 8
    DO WHILE r < 8
        DeathAnimation 0, 0, r, c
        r = r + 1
    LOOP
    IF r >= 8 THEN r = 0
    c = c + 1
LOOP

SUB DeathAnimation (x, y, r, c)
    _LIMIT 20
    rh = 200 * r + 1
    ch = 200 * c + 1
    CLS
    _PUTIMAGE (x, y), deathss, 0, (rh, ch)-(rh + 200, ch + 200)
END SUB

Then make rectangular selections around the picture elements to get the top and left coordinates, and the width and height of each sprite. This promises a long time of hard work, and experimentation and it's not for the lazy. The considerate people creating the sprite sheets create sprites that require the same width and height which would make programming easier, but the sprites have to be gathered correctly. You have to watch out because some larger screen elements (like a boss in an arcade game) could occupy two or more squares of an "unit" in the sprite sheet.
