Change to:

print"<a href='pictures/$file'>$file</a>";

If you want to display the image then you have to do something like

print "<img src='pictures/$file'>";

I've reformatted your code which will let you find one error easily
and added a few comments (the ### lines)

<?php
$handle = opendir('pictures');
if ($handle) {
while (false !== ($file = readdir($handle))) {

### this will match foto5jpg without extension;
### probably you will not have such a filename in the directory
### but you may want to remove the () and escape the .
if (preg_match("/\w+(.jpg)/", $file)) {

### when someone clicks the filename do you want
### them to go to the "pictures" directory?
### AND check your quotes
print "<a href='pictures'>"$file"</a>";

### Why are you printing $file twice?
print "$file <br>";
}
}
closedir($handle);
}
?>

You gots to look at the html that is produced by this code, and see if
it makes sense: <?php

$handle = opendir('pictures');

if($handle) {

while(false !== ($file = readdir($handle))) {

if(preg_match("/\w+(.jpg)/",$file)) {

print"<a href='pictures'>"$file"</a>";
So where is this link supposed to go? Maybe you wanted "<a
href='pictures.htm'>"?

print "$file <br>";

Did you want this to print the actual image, or just the name of it?
If you want to see the image, you would do like:
print "<img src='myImageDir/$file'>";

Just one more thing ...

preg_match("/\w+(.jpg)/", $file)

will also match "rejpg.doc"

cheers for all your help.. the code works now.. but it only loads two
images despite there being more in the directory.. any ideas why this
is? im looking to post about 7 pictures... heres the new code:

<html>

<head>

<title>

My wonderfully great pictures

</title>

</head>
<body>
<BODY BGCOLOR = "green">
<pre>
<h1> Photo Gallery </h1>

Click on the link to view image in separate window
</pre>

<?php

$handle = opendir('pictures');

if($handle) {

while(false !== ($file = readdir($handle))) {

if(preg_match("/\w+(.jpg)/",$file)) {

print"<a href='pictures/$file'>$file</a>";

print "$file <br>";

}

}
closedir($handle);
}
?>

Don't be a dope--use glob():

$files = glob("pictures/*.{jpg,JPG,jpeg,JPEG,gif,GIF}", GLOB_BRACE);
foreach($files as $file) {
$filename = basename($file);
echo "<a href='$file'>$filename</a><br>";
}

http://fi.php.net/glob/

P.S. The reason you're not seeing the other pics is probably because
you're using a case-sensitive regexp.
