Hi friends,

I have 6 pictures. I want some of them appear on the form by clicking command button.

The important point is the same pictures won't appear in each click.
For example,

First click, picture-1, picture-2, picture-3, picture-4 will appear
Second click, picture-3, picture-2, picture-5, picture-6 will appear
Third click picture-4, picture-5, picture-6, picture-1 will appear

etc...

How can I do this?
