ELI5: Explain Like I'm 5

Mipmap

Mipmaps are something you can use to make images look better. They work by having multiple versions of the same image at different sizes. This way, when you need to show the image on your screen, you can use the correct size and it will be sharper and clearer. It's a bit like having the same picture in different sizes for different situations - like having a small version for your phone, a bigger version for your computer, and a bigger version for your TV. It makes things look much better by using the correct size for the job.
