Yes, the image is like a "snapshot" of RAM with live objects in it. So
an image is not the same thing as for example a jar-file in the Java
world which is just a bunch of class definitions - not objects.

BUT... you can still start the Squeak VM with an image AND a "script"
file fed into it on the command line. The VM then starts the image which
in turn has standard mechanisms to examine the command line starting it,
extracting arguments and possible opening, compiling and executing
Smalltalk statements found in a file given as a URI on the command line.
