Animation problem.

Looking through my user pictures, I realized I don't have a crack icon (for lack of better terms). So I cranked out this today:

Here's my issue, though. The icon is supposed to be a LOT faster than that. It consists of four frames, all set to 0 delay. When I play it back in ImageReady, it's a speed-demon. So, I optimize it, save it, upload it, but then it's going slow, like that! So my question is this: is this a problem with ImageReady, or just a freak accident?

As a side note, does anyone have any ideas to make it a bit more...eh, for lack of better words, 'chaotic'? I have the feeling that the random placement isn't really doing it.

As usual, thanks in advance for any help!
