A few days ago, I bought a Gatsby blog theme and tried to modify it. The blog site uses Images(PNG, JPEG), not animated GIFs. So I tried to use GIF images for all blog posts but it affected site performance.
Also, I notice that [Gatsby Image](https://www.gatsbyjs.com/plugins/gatsby-image/) doesn't provide a GIF format. How can I use GIF on my blog with high performance?
