The problem with this is, if I convert the images to gifs, the
quality will be drastically reduced, thus leaving me with a nasty
looking animation. Ultimately, I would like to create an animation
with the separate images that I have.
I do not need a 30fps animation, 10 would probably suffice. Its just
where to start???
Thanks,

why not have a NSImageView with a GIF of your animation in it and
flip setAnimates: depending on when it should be in progress or
not? That seems like it would be the easiest solution, albeit
somewhat limited.

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.

The goal of this is to create in some sense, a custom progress

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
