For this recipe, we need a sprite sheet with multiple images on a black background. Either use one of your own or use the fire2_64.png blue flame sprite sheet from Open Game Art. Thanks to Ben Hickling for sharing this asset for game developers to use.
We've prepared the file you need in the 14_03 folder. Alternatively, you can download the sprite sheet image file directly from the Open Game Art website: https://opengameart.org/content/animated-fire:
