My home page starting clip art will not animate.

I think you resized the image using CC edit tool. CC resizing only saves ONE image in a GIF. So that got rid of the other images required for animation.

Instead of using CC resizing, re-upload the image, then add the WIDTH in source mode and it will then animate.

Here's how you do it (replace with YOUR file vault link - this will work for a bit but is on MY site. Your link will only have the stuff starting after classcreator.com - if you look at your existing source you can see what that looks like.
