Well.. alot of the questions you've asked in this thread have quite complex answers, but those answers are very easy to find/work out yourself.

Can you serve two pages to two different browsers? Yes. Can you put the image in a div popup? Yes.

Personally, I'll give hints on how to do things, and if it's non-intuitive and can be explained with a code snippet, I will give that code snippet. I won't however write out a large amount of code that demonstrates something that's technically very 'simple', especially not when there's a multitude of examples of these very things easily available on the web.

You're evidently able to work this stuff out for yourself if you give it a bit of thought.
