I know you admit it's not the most efficient, but if you had alot of thumbs to convert, I would think you would be better off doing it all in Perl, and not calling convert thru system for each image. The ImageMagick object can be created once, cleaned out of data, and reused for the next image. I havn't benchmarked it, but I think it would be much more efficient that way. For anyone looking, it would be done something like this, to reuse a single IM object. 
#!/usr/bin/perl
use warnings;
use strict;
use Image::Magick;

my $image = Image::Magick->new;
umask 0022;
my @pics= <*.jpg>;
#my @pics= <*.jpg *.gif *.png>; #add all your extensions here
   
foreach my $pic (@pics){    
   my ($picbasename) = $pic =~ /^(.*).jpg$/;
   my $ok;
   $ok = $image->Read($pic) and warn ($ok);
   my $thumb = $picbasename . '-t.jpg';
   $image->Scale(geometry => '100x100');
   $ok = $image->Write($thumb) and warn ($ok);
   undef @$image; #needed if $image is created outside loop
   print "$pic -> $thumb\n";
}
