Can we do the compression check more generally? I'd like to be able to see Image.xz/lz4/etc be able to be handled cleanly. When you say the compressed file, you do mean the Image.gz (for example) itself, right? I would suggest documenting using $filesize after loading the compressed image as that should always be set.
