Im trying to use a gallerific slideshow and want to use perl to open any image in the directory and make the slideshow. It works if i dont use the for loop but as soon as use the for loop it stops working. any help would be appreciated.

here is the code:

<color red>
#!/usr/bin/perl
use strict;
use warnings;
use CGI;
use CGI::Carp qw(fatalsToBrowser);

print "Content-type: text/html\n\n";

print <<startHTML;

var hash = this.href;

\$.historyLoad(hash);

return false;
});

</script>
</body>
</html>
endHTML

if i replace the for loop with the following it works fine:
<color red>

<li>
<a class="thumb" href="../images/featured/small_featured/Spino 182.2.jpg" title="Spino 182.2.jpg">
<img src="../images/featured/small_featured/Spino 182.2.jpg" alt="Spino 182.2.jpg" / width="50" height="50">
</a>
<div class="caption">
<div class="image-title">Spino 182.2.jpg</div>
<div class="image-desc">Description</div>
<div class="download">
<a href="../images/featured/small_featured/Spino 182.2.jpg">Download Original</a>

</div>
</li>

Try using "foreach" instead of "for".
