non vector blank panel art

hi, i would like to make a group of blank panels with hand drawn art done on an ipad in procreate. these would not be .svg, what is the proper way to create these? i notice modular fungi has blank panels that dont appear to be vector based and computerscare created a blank panel that allows you to drop your own image file onto it. how are these done? has this been discussed before? if so, can anyone point me in the right direction?
