Saving a puzzle mid-way.

[Chimbo]

I'm looking for a way to save a puzzle mid-way.
This, for me would be the script of a scripts, as I have about 10 or so puzzles on my site. 1 24-piece, and the rest 96-piece puzzles.

The other issue was something to let me know when it's solved, but I prefer the first one (saving my work).

Using this puzzle script:

Quite simply put, saving is not possible using javascript on the web. It could be achieved if:

*The site is local only (stored on your machine)
*You have access to a server-side language (php, perl, etc.)
