Adding an Image to the background during a Hyper Attack

[SirGomezPipi]

Hello. I'm fairly new to Mugen. I've come across some characters who have huge images of them appear in the background while they perform a hyper combo. I'm curious as to how this is done. Can someone explain please?

type = Explod
trigger1 = Time = 0
ID = 8500                  ;change this
anim = 8500              ;change this
postype = left
pos = 0, 0
bindtime = -1
removetime = -2
supermovetime = -1
sprpriority = -4
ownpal = 1


some people use a lower sprpriority so things might not go behind it. You just use a normal animation with no hitboxes and make it an Explod. Set it to go off when the ultra starts
