Specifically, the two gifs you posted with these links:

I understand you guys have a problem with some links I posted.Although they work fine for me from the country where I live, ( independent of ISP and PC at work and at home ),I added and changed some links to alternative pictures. I keep the other links for the time being.

The concept is simple and when you see it, you understand it.
The use of two lenses requires some experimenting but obviously increases throw.

I understand you guys have a problem... :nana: As you understand for me all pics and links work fine.

Because they were on YOUR network you nana. :twak: :whoopin:

Thanks for fixing them. :clap: Although... you've left the bad links there. :ohgeez:
