. and .. appear instead of pics

First of all, thanks very much for providing this forum. It is very much appreciated!
My son-in-law created a php script for my website about 10 years ago to show pictures like a manual slideshow, and it worked fine for many years. I just recently discovered that it now has a problem and I wonder if it has to do with this host having different parameters.
The problem is as follows:
The first pic shows a . , the second shows .. , and the third shows the first pic, the fourth shows the second pic, etc.
I need to get rid of pics 1 and 2 which are displaying as . and ..
My son-in-law told me to add a # before @files in the
#remove the .. and . directories
and it should remove the dots but it does not. He can't think of any other suggestions. The full code is as follows:
#!/usr/bin/perl
#this script will act as a type of slide show
use CGI;
if(CGI::param('directory') eq undef) {
print CGI::header();
open(F, "pictures.txt");
chop(@directories = <F>);
close(F);
foreach (@directories) {
my($pDirectory, $title) = split(/::/);
my($hrefTitle) = $title;
$pDirectory = $pDirectory;
#remove the spaces
$pDirectory =~ s/ / /g;
$hrefTitle =~ s/ / /g;
print " <A HREF=\"/cgi-bin/pics.pl?directory=$pDirectory&title=$hrefTitle\">$title</A><BR>";
}
} else {
#variables
my($serverRoot) = "/home/ma3ry/christiangays.com";
my($directory) = "/" . CGI::param('directory');
my($i) = 0;
my($max) = 0;
my(@files) = ();
$i = CGI::param('picNum') unless(CGI::param('picNum') == undef);
#open the directory
if(opendir(DIR, "$serverRoot/$directory")) {
#read in the contents of the directory
my(@files) = readdir(DIR);
#remove the .. and . directories
#@files = splice(@files, 2);
#sort the files
@files = sort(@files);
#find out how many pics there are
my($max) = @files *1;
#build the page
&createPage($directory, $files[$i], $i, $max, CGI::param('directory'), CGI::param('title'));
#close the directory
closedir(DIR);
} else {
#directory is not found
print "Content-type: text/html\n\n";
print "Couldn't open directory $directory!\n\n";
}
}
exit(0);
sub createPage {
my($directory) = shift;
my($picName) = shift;
my($i) = shift;
my($max) = shift;
my($hrefDirectory) = shift;
my($title) = shift;
my($j) = $i - 1;
$i++;
