When you ask the question like that, no, but I've made strides:

 $ perl mpj4.pl
file: /home/dan/Desktop/upload/382432_10150873103536275_1105470601_n.j
+pg

$ cat mpj4.pl
#!/usr/bin/perl -w
use strict;
my $path = '/home/dan/Desktop/upload/';
my @files = <$path*>;
my $counter = 0;

for my $img (@files) {
  $counter++;
  print "file: $img\n";
  my $ext = ($img =~ m/([^.]+)$/)[0];
  print "ext: $ext\n";
  my $filename = "$path" . "image_". "$counter" . '.' . "$ext";
  print "filename: $filename\n";  
  rename ($img, $filename) or warn "couldn't rename $img to $filename:
+  $!\n";

}

The situation that was really throwing me for a loop was that I'd write something to rename things, and then they'd all disappear. Until I put the asterisk in the diamond brackets, the directory did too! From what I read last night, this is something that happens to every perl learner at some point. I'm sure there's other ways of doing this, and I'd love to see them. I'll take a look a look at File::Copy when I get back to it.

I wanted to say a few words on where I'm going with this. I want to combine these scripts so as to have a directory that has renamed images, but with the correct extension:

$ perl lh1.pl
downloaded 4 images from https://sites.google.com/site/lutherhavennm/m
+ission
to folder site_8
$ cat lh1.pl
#!/usr/bin/perl -w
# creates a new directory and downloads images from url to it
# perlmonks node 965537; thx aaron and A.M.
use strict;
use feature ':5.10';
use WWW::Mechanize;
use LWP::Simple;
use Errno qw[ EEXIST ];

# get information about images
my $domain = 'https://sites.google.com/site/lutherhavennm/mission';
my $m      = WWW::Mechanize->new();
$m->get($domain);
my @list = $m->images();

# create new folder and download images to it.
my $counter = 0;
my $dir     = &mk_new_dir;
for my $img (@list) {
    my $url = $img->url_abs();
    $counter++;
    my $filename = $dir . "/image_" . $counter;
    getstore( $url, $filename ) or die "Can't download '$url': $@\n";
}

# output
print "downloaded ", $counter, " images from ", $domain, "\n";
print "to folder ", $dir, "\n";

sub mk_new_dir {
    my $counter2 = 1;
    while (1) {
        my $word = "site";
        my $name = $word . '_' . $counter2++;
        if ( mkdir $name, 0755 ) {
            return $name;    # success, return new dir name
        }
        else {
            next if $!{EEXIST};    # mkdir failed because file exists
            die sprintf "(%d) %s", $!, $!;    # other failure; bail ou
+t!
        }
    }
}

After that, I want to create an html file that will have the stubouts for these images and their caption, but that has to be tomorrow. Cheers,
