    base-item: Save everything other than PNGs as JPEGs
    
    This is a reasonable strategy to start with. It let's us avoid writing
    size guessing code for every possible image format out there. Apart
    from RAW images, PNGs and JPEGs are the most common formats out there,
    and JPEG is a good option for exporting RAWs.
    
    We can add support for more formats as we go along.
