I used the example from this link:
http://www.jkp-ads.com/articles/showpicture00.htm

because I didn't have the version of excel after 2003, and I noticed that
using multiple dynamic pictures causes the PC to lag alot, I used 36
instances of this and makes me wait a certain delay between each edit in any
of the cells while they're visible.

I wonder if using the one that requires VB would make it any faster.
by the way I tried several PCs with varying processor powers and I noticed
that almost same delay no matter how the processor is powerful.
