Optical illusion - images

Bruce: Thanks. I tried that several times with no success.
I guess I need guidance on whether to keep posting links or just forget it.
Even if I could get your technique to work, I am not sure how long it takes.
I can post a link quickly and easily and opening them is a matter of seconds.
If anyone feels what I post is not usually to their liking or does not want take the time, they are easy to skip.

I get a black box for videos, but have developed a cut and paste technique (for YouTube, anyway) that takes under a minute.
A link would be faster for my IE system.
I will be content to continue my way if it is not causing trouble.
