Hi Jerry-
1) It appears that it might be possible to change the type of cell
in the NSMatrix after the app starts up, true? The scrollview has
to "fit" in the UI so creating the objects from scratch sounds
too painful.
Definitely possible. I was helping someone with a similar question
some time ago; details and code snippet are at:

2) Has anyone observed any performance difference between the Matrix
approach as opposed to the table approach?
I have been using the matrix solution - I can tell you that you want to
put thumbnails of images in the image cells, not the full sized image.
Scrolling suffers if the contents of the cells have a lot of bytes...
If you like, email off list and I can send you the class files I am
using - I'm sure you can mess with them to get your desired
functionality for yourself, and they also include some abilities that
don't come with image cells (i.e. target/action so that they are
clickable like a button).
Hope this helps!
John
