image size / viewer size

[virtualgeorge]

So lets say that you have a viewer window size set to 400 x 300 with a fullscreen button.

For the pano to look good in fullscreen mode you would want your pano size about 5000px wide correct?

But when viewing that 5000px wide pano in the 400 x 300 window I see distortions or rippling, not sure what you call that?
If I use a pano of 2000px wide in a 400 x 300 window it looks much better.

So if you are using a smaller size viewing window would you normally have 2 different size panos and can you have the fullscreen button load a different pano so you could have one pano load in the small window and another load for fullscreen?

thanks!
