Quit GraphicConverter, open the CD by double clicking on it, move the  
relevant files to disc, and open the files by clicking on them.

The Mac chooses the correct application to open a file by appending a  
four character file Type and a Creator code to the file name. These  
codes are usually invisible. Your images on the Photo CD are probably  
typed as JPEG and the creator is typed as GKON. The application  
GrapicConverter is called when a file with a GKON creator code is  
opened. If you want it to automatically open in a different  
application, the answer is to change the creator code in the file.  
There are a number of small applications which will give you access  
to the codes. The one I use is an older one, File Typer 4.0. You can  
get a variety of similar applications on To  
make the file open in Preview, change the creator code to ogle. Case  
is important.

I'm sure there is a more sophisticated, and probably more correct,  
answer to your question - but at the moment, it escapes me. Not to  
worry, some of the programming types will offer better advice.
