Hi skyzyk !
just consider the preview as a wallpaper with 1\ 2 AnimatedIcon frames inserted in the middle
also you can take a screenshot of ObjectDock running the AnimatedIcon at the maximum icon size: 256 pixels (BTW it seems that the frames are 70x70 I suggest a larger size)
naturally you can load 2 times the same icon or even 2 single frames (just drag&drop the images on the dock)
as always the preview is .jpg format, suggested minimun size 800x600 automatically resized on the gallery page,
hope this help ... waiting for your entry in the AnimatedIcons Skinners Club !
