Wander through a directory, looking for jpegs, first renaming anything with a space in the name to that name with underscores and jpeg. Find the un-thumbnailed ones, create a thumbnail suffixed with ".thumb.jpg". Uses ImageMagick.
#!/usr/bin/perl
use strict;
use Image::Magick;
my $im = Image::Magick->new;
umask 0022;
my @names = @ARGV ? @ARGV : grep { -f and -B } <*>;
for (@names) {
if (/ /) {
my $old = $_;
tr, ,_,s;
$_ .= ".jpg" unless /\.jpg$/;
! -e and rename $old, $_ or next;
warn "renaming $old to $_\n";
}
next if /\.thumb\.jpg$/;
my $thumb = "$_.thumb.jpg";
next if -e $thumb;
undef @$im;
my $ret;
$ret = $im->Read($_)
and warn($ret), next;
$ret = $im->Scale(geometry => '100x100')
and warn($ret), next;
$ret = $im->Write($thumb)
and warn($ret), next;
warn "thumbnail made for $_\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
