Once toast burns the 'saved' image from the inserted, copied disk, it 
retains the image, after the burned disk is ejected. It might even 
ask if you want to save? Usually i click, no, and toast quits, but 
before the quit, whenever there's a 'saved' image [still visible as 
the title, inside the toast window], i get the "Save?" prompt. This 
leads me to believe that one could easily click on "Burn", again and 
then insert a new disk, etc...
