have a look at the MenuIcons
because the icons are stored as methods.
"self importIconNamed: 'Icons16:appearanceIcon'"

writer := GIFReadWriter on: (FileStream fileNamed: aString,
[ image := writer nextImage]
ensure: [writer close].
stream := ReadWriteStream on: (String new).
stream nextPutAll: aString ; cr.
stream nextPutAll: (self methodStart: aString).
image storeOn: stream.
stream nextPutAll: self methodEnd.
MenuIcons class compile: stream contents classified: 'accessing
