I'm no expert of any type and even less when it comes to flash applications, i'm quite sure though, that the .pngs, .jpgs, whatever be, already exist, and flash loads them.
Maybe decompiling a .swf allows to get some of the images but catching the .swf at any time probably gets the login part, not the animations you're actually seeing it when you save it in your computer, which brings us to the problem "images not loaded".
So i guess you would have to ask zanzarino to send you the image files.
Note: Again i could be wrong. Don't put your hands on fire for what i said ;x I "iz" a learner
