Shishi Sprite Editor Error

[HackTastic]

Ok So this is my first time replacing sprites and I just wanted to play around with the looks of the sprites. i want to replace ramza with the Altima Second Form sprite. I exported the SPR then I tried to import it and replace the ramza sprite, but it said that it was too big and that the max size was 45056 bytes. I am unsure how I am suppose to reduce the size, so is there any way i could possibly reduce the size so i can use it? Much help would be appreciated thank you!

You can't. It's one of the many downsides of modding WotL.
