David,

Thank you for explaining how to do the export with ExpressionCell.

I have a two part followup:

1) I want to do hundreds of these files, and would like to use a table
and variables which change. Is it possible to use "m" and "n" within
the ExpressionCell[Defer[1 + 91}, for example, so that I don't have to
rewrite each export statement?

2) I would like to make the file names dynamic. For example, if I am
adding 1 + 91 = 92, I would like to name the file 01019192.jpg, where
the leading 01 stands for addition, and the remaining string 019192
stand for 1, 91, and the sum, respectively.

As an example, I would like to be able to write one statement to
create 14 jpg files for the "14's" times tables, 1 x 14 = 14, 2 x 14 = 28, ..., 14 x 14 = 196.

Thank you for your time,

Diana M.
