Just looked into AChecker. It’s saying that I’m missing the alt= in the image tag, but it’s already there. I checked.
No, if you want to keep animation on your page, then
give their control - ( on/off ) - to your visitor.
As a matter of interest your imge in post #15 is 3.46MiB.
If you converted it to mp4 video here…
…the file size would be 1.44MiB, a 58.48% reduction.

Ok I’ll convert it again. How do I put in the on/off controls?
Managed getting it down to 1.33 
But now it won’t let me upload to imgbb’s website. It doesn’t accept it.
