So it would be better to create a single image with all the frames
included? How much more efficient would this be over creating an
animating with say 10 separate images.
Thanks,

What's commonly done in this situation is to have a single image
which contains all your 'frames'. Then, whenever your indicator
needs to update itself, just compute the new frame index and use
that to determine the source image bounds.
Here's a small piece of code from a tiled-graphic object:
NSRect theTileRect = NSMakeRect (theColumn * theTileSize.width,
theRow * theTileSize.height,
theTileSize.width, theTileSize.height);
[theImage drawInRect:theDestinationRect fromRect:theTileRect
operation:NSCompositeSourceOver fraction:1.0];
where theTileSize (NSSize) is the dimensions of an individual tile
(frame)
where theColumn and theRow are 0-based indecies
