Hi Duvy, you need to get into designing stuff on Canva. Ask your neice and I am sure that she will know how to use Canva. You can upload images and animate them on Canva and then download those images as animated GIFS, in JPG format. Canva is so much fun for creating posters, videos and so many other things. I love Canva. :)
