@JosefSábl, GD has been phased out more than 6 years ago; the question of backward compatibility is no longer relevant. – Jacco Jun 08 '16 at 06:49

Some version of GD generates only PNG, but recent version can ganerate GIF and PNG. Soon GD 1 will be no longer supported in next version of PHP.

GD 1 will no longer be supported. That makes sense. GD2 support will stay. – Jacco Jun 16 '10 at 21:06
