I do not know what you mean there. David was saying that a problem is
that these images seem to be RGB, thus probably their values are not
intensities, but colors derived from a single channel image (the
intensities) mapped through a colortable.

That is simple. The array arm would be too big to fit in memory. If
you have RGB images with 2216x1254x3 bytes, each is just short of 8MB,
so probably a few hundred of those would be enough to fill your
available memory.
