Originally this provided filtering for the novice user to open 
particular kinds of files. In 2003 it was updated to use the services 
registry rather than the hard-coded descriptions and methods. At that 
time it was also modified to use the the suffixes for graphics files 
generated by ImageReadWriter subclasses rather than the static list in 
the method. Which basically changed this

'bmp' 'form' 'gif' 'jpeg' 'jpg' 'pbm' 'pcx' 'png' 'ppm' 'xbm' 'xpm'

into this

'bmp' 'gif' 'jpeg' 'jpg' 'pam' 'pbm' 'pcx' 'png' 'pnm' 'ppm' 'xbm'
