I think this post
http://gbracha.blogspot.com/2009/10/image-problem.html
shows the advantages and disadvantages of images pretty well.
In GNU Smalltalk, the image is used mostly as a cache of preloaded
packages. It allows very fast startup because all the code is already
compiled and converted to objects (instances of Class, CompiledMethod,
etc.). See also
http://smalltalk.gnu.org/faq/37
which expands a bit on this topic.
