That's ~10,944,512,000,000 possible images.

I recently wrote a windows program using one of the new Icons and the Icon embedded in the program was bigger than the executable code...

length*width*colors isn't right. You are finding the area, then multiplying by the total possible colors. That is the number of times when all pixels are the same color. You're leaving out all else. It would, in fact, be much larger: 16,777,215^(256*256). It's so huge, I don't even want to post it here, because of it's massiveness would span a couple pages.

Oh come now! 256*256*log 16777215 = 473479.2414, so it's only 473480 decimal digits long. Even if we assume 160 characters a line, that's still 2960 lines. At 50 lines a "page" that's more like 60 pages.

"Couple" is indeterminate. Point is, it would be inconsiderate to post such a monstrous glob of digits. (That, and my perl script(using GMP for BigInt) was taking a REALLY long time, and my computer was getting REALLY hot. So I killed it, and decided to leave it at that. )

I like maxorator's explaination, it's more mathy than mine.

I was trying to make a calculator that did this, but how do you make a variable that can hold 473480 places? who ever makes this will probably have to make their own picture viewer instead of waiting for windows media player to open, that would take a while...

You have to use a bignum library or calculator. I use Perl for simple stuff like this because it has pretty seamless bignum integration. There are some bignum calculators available on the internet, some in Java so you can use them right on the website.
