Hmm, usually an image file has a header that describes some meta data about the image: version, some VM options, size of the image��

If you load:

Gofer it
    squeaksource3: 'ImageWriter';
    package: ���ImageWriter-Core';
    load.

You��ll get HzCogImageFormat that describes the header. Check the method writeImageHeaderOn: byteStream forWriter: aWriter

Hi,

from a Pharo image, can I detect if another image needs the Spur VM or
not?

Best
