Answer 4

This is not possible with javascript. You need to use GDLib or some other server side image manipulation library.

Answer 5

I'd say your best option here is to use something like flash, java, etc. JavaScript MIGHT be able to do this, but it will never be able to do it WELL. It is better to use a technology that has the power to do what you are asking without being stretched to it's limit.
