The different ocr engines differ on which formats they supported, but 
install imagemagic and use a command like
convert file.jpg file.png
to get the image into the correct format for the engine.
ocropus used to require png but I susspect now-a-days it might accept 
other image formats too.
There are some test images with most engines when you build from source.
