Make animated sprites?
You would have to make the individual frames in an image-editing program, SprWizard isn't an image editing program.
You can also decompile existing sprites to edit them, animated or not, with SprView, another nifty little sprite program. Look around for those two programs.
Once you've got all of the sprite's frames, you put them all together into a .spr file with SprWizard. If more than one frame is selected, then it'll make the sprite animated. If you only select one frame for the sprite, then it won't.
