Thanks to all of you who answered my question about picture fields in dialog 
boxes. It really helped :) 

But now I have another problem : my program needs to accept any type of file 
dragged from the finder . I made a type of **** in my BNDL resource; it 
worked well on my performa, but when I tried it on my PowerPC, no file could 
be dragged from the finder in my application. What should I do ?
