Gifs in Rise microlearning

Hello, 

I'm trying to create a microlearning and upload a GIF however I can't see where i can do that. 

When I try to do so within for example an image and text block it asks me to check the formatting of the image is a jpeg. 

I've seen a rise module with this is as an option within the content library so I know it can be done but struggling to do it myself. 

Thanks
