How did you create the GIF, I see the code and it outputs only one image... did you use Wolfram too to export a GIF consisting of 8 evaluations of that cell?
I think it is as simple as generating 8 random images, putting them in a list and exporting, something like this probably:
Export["animation.gif",{img1, img2, ...}]
