You are right: I fixed my code and it works (on Mac at least, I'll test 
GS quite soon)! I also went the extra mile: If only one object is 
selected and I have an Image, I provide both the custom image type with 
the plist and encoded representation as well as the bitmap image rep, so 
that the image itself is available for other apps. So you could copy an 
image back ad forth e.g. to PhotoShop. Quite cool :)

Look at what you can do with it now:

For the next Graphos release I want to enrich also the file format to 
save images and thus allow mixed vector and bitmap content.

I see two ways:
1) write the same plist with the encoded NSData to disk.  I fear that it 
is slow and inefficient. I also fear that the format is not portable 
between Mac and GS! could that be? I want of course files to be 
exchangeable between Mac and Linux, that's the strength of the app! 
However it would be very easy to to do: that's how all other objects in 
Graphos work
2) make a bundle format like RTFD, thus save all images inside the 
bundle. I guess that is faster, is portable between Mac and GS. It 
always need to be zipped when transferred via FTP, web, ssh....

What do you think? I did non try yet the TiffRep compatibility between 
Mac and GS, but I know that NSColor is incompatible for example.
