This is a guide about images.
It is recommended to use ".png" as it is the best, although for animated images you must use ".gif".
These are some of the common image types.
|.jpg||This image type can't have transparency. And it usually distorts the image. Can't have animations.||Very Bad|
|.gif||This image type can have transparency. But it sometimes slightly distorts the image. Can have animations.||Ok|
|.png||This image type can have transparency. And it does not distort the image. Can't have animations.||Great|
