This is a port of the plugin ImageFireworks by deantonious (https://www.spigotmc.org/resources/imagefireworks.18932/) that I have ported to Spigot 1.11.2 and below and have added new features.

Credit to deantonious for making the original 1.8 - 1.10.2 plugin. All I did was add and modify his code. Without his amazing work this would not have been possable!
