Hi again. Just to demonstrate the speed up from using Storable, I chopped down the script I mentioned above, so you can see the basics. Just run it in a directory with some jpgs in a subdir called "pics". The first run will be slow as the thumbnails are built, but exit the program and restart. The second run will be very fast by comparison.

if(-e 'notebook.db'){
     %info = %{retrieve('notebook.db')};   # direct to hash 
    }else{ make_thumbs() } 

#to see a dump of the db, just put an 1 as an arg to the script
if(shift){print Dump(\%info);exit;}

my $mw = MainWindow->new(-bg=>'black');
$mw->geometry('800x700+100+15');

#setup auto save of storable db
