Is there an easier way to change boot animation.??

[JDM_SOHC]

I've tried to read the instructions over on XDA but that thread is so cluttered it's crazy and almost unreadable..

I found a kick ass animation I want to put as my boot animation but I'm used to the windows mobile days where it was just rename, copy, paste, done... Now with Android it's seemingly a bit more involved... Someone said I have to flash it like I would a ROM or something, but that right there just confuses me because how do you flash an image..?? I've searched for more help but can't find anything but useless clutter, if anyone knows of maybe a 1, 2, 3 step method I'd appreciate it...
