Placing a gif on an image banner. Support needed :)

[Malakush]

Greetings, 

I would like insert a gif overlay on to the left side of my "Image Banner." Currently there is a minimal geometric design that I would remove and place the GIF in it's place. Would someone be able to assist with the code for this? 

Many Thanks 🙂
