[Coco] Is there a way to import JPGs or BMPs to a CoCo picture file format that can be used in a program, game etc?

I know there are viewers but are there applications that preferably can run on a PC and convert JPG,BMP etc files to a Coco picture file say a CoCo 3 picture file that one could then use in a program, game etc? If so please let me know where I can obtain or preferably download it from thanks...
