In that perfect world where we all live together in perfect harmony, the sky is always blue, the grass is always green, and VB never came into being, yes, there is a JavaScript get() function.

In the really real world, though, such a thing would be considered a munition. Your browser could be commanded by a third-party to do whatever they choose, such as probe sites with IIS attacks, send files from your computer, or just cause general mayhem (i.e. DDOS).

There is no "get()" function, no.

With a little creativity, though, you can swap images in a clever way to simulate animation and/or server-side loads. Check your JavaScript reference on how to do this, because this is clearly not a Perl question at this point.
