FW: Bitmap-Arrays too large for "contents"

The Problem now is, that some of my images generate more bitmap-code elements than "contents" can display. Do you have an Idea how may copy&paste all the elements of the Stream!? I tried Seaside WAFileLibrary and pasted the generated methods, but WAFileLibrary returns byte-arrays, which can't be interpretet within the squeak form of *Morph.

 Hi Bert & Squeak Community,
 thanks for your cool tip. I'll try to generate the methods via "class compile".
 I've tested it and a new problem came up. I did it the same way MenuIcons>>importIconNamed is implemented.
 The problem now is, that there comes up a error message ("MessageNotUnterstood(Metaclass)>>category") although I've inserted classfied : 'generated methods' and the category is already created and exists.
 
 Here the code snippet:
 
 generateMethodsForJPG: aString
 | writer image stream |
  writer := JPEGReadWriter on: (FileStream fileNamed: aString, '.jpg').
  [ 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.
  MyGraphicLibrary class compile: stream contents classified: 'generated methods' notifying: nil.
  ^ stream contents
 
 MyGraphicLibrary is a subclass of Object.
 The error comes up at "compile:[...]". Everything before that works fine. Form is created etc. Simply the compilation does not work.
 
 Do you have an Idea what the problem could be here ?
 
 Thanks for your help!
