Then there's the option of animating the SVG file itself. There is a number of online tools to do this, or you can use the software of your choice. Once your SVG is animated and ready to go, you then upload it like any other image to your WordPress media library. When you embed it on a page/post, you will need to make sure to add the class to the IMG tag so SVG Support can render it inline. This will ensure your animations are displayed.
