Thanks Monks!!! @row_entries= splice (@piclist, 0, 5); was a new concept for me. It doesn't appear in Learning Perl and is only given a cursory glance in Programming Perl.
The final code for this is below. Just set the root of your images directory. Simple and quick. I tried to keep the code readable (and because I'm still a Perl novice).
This displays 5 images per row, then it starts again (thanks Randal!)
Just before the image src HTML, I'm stripping off the full path and assuming the image path is /images/$_
$startdir="/www/intranet/images";
push(@dirs,$startdir);
foreach $dir (@dirs)
{
opendir(DIR,"$dir") || die "opendir $dir failed";
@list = grep(!/^\.\.?$/,readdir(DIR));
closedir(DIR);
foreach $item (@list)
{
$fullname = $dir."/".$item; # add the directory name to th
+e file name
if (-d $fullname)
{
push(@dirs,$fullname);
print "$item<br>";
}
}
}
print "Content-type:text/html\n\n";
&parse;
print qq|
<html>
<head>
<link rel="stylesheet" type="text/css" href="/include/style.css"/>
</head>
<body>
<p>
<form action=/cgi-bin/images.cgi method=post>
<select name=pic>
<option value=$FORM{'pic'} selected>$FORM{'pic'}
|;
foreach $thisdir (@dirs)
{
print qq|
<option value="$thisdir">$thisdir
|;
}
print qq|
<input type=submit value="Go!">
</form>
</html>
|;
opendir(DIR,"$FORM{'pic'}") || die "opendir $dir failed";
@piclist = grep(!/^\.\.?$/,readdir(DIR));
closedir(DIR);
print "<table cellpadding=10 cellspacing=0 width=100%>";
while (@piclist)
{
my @row_entries= splice (@piclist, 0, 5);
print "<tr>";
for (@row_entries)
{
print "<td>";
$FORM{'pic'} =~ s/\/www\/intranet//;
print qq|
<img src=$FORM{'pic'}/$_><br>$_<p>
|;
print "</td>";
}
print "</tr>";
}
sub parse
{
read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
@pairs = split(/&/, $buffer);
foreach $pair (@pairs)
{
($name, $value) = split(/=/, $pair);
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$FORM{$name} = $value;
}

This is totally cool! I have been working on a vary similar thing for a web-based photo gallery. I had users picking a category (directory) from a form, then generated a page of images and text description by

I thought this code was really neat because I was working on something similar. So I took it and made some changes, that hopefully improve it.
I also broke it up into two files because of some of the other things I'm going to add for my specific project.
I would be interested to know if anybody else has suggestions on how to make it better, just to help me learn.
Also, even though it works for me, I really don't understand what the line $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg; is doing. If anybody can help shed some light on that, I'd appreciate it.
