Hi, I'm using Imageviewer by Trent Williams (http://www.codewalkers.com/c/a/Site-Navigation-Code/Simply-image-viewer-script/)
How would I get rid of the extention of the file from printing out?

I'm hoping to be able to explain the image in its file name but having, "explosion in a alley.jpg (http://www.plentyoftorrents.com/imageviewer/imageviewer.php?id=6&thumb=yes)"
Doesnt really look that good.
I'll be using it to display funny animated gifs, and pics in my Bittorrent flash humour site.
Any help would be appreciated. :)

Heres the code:

<?php

//=========================================
//
// Author: Trent Williams
// Date: 19 Aug 2005


// EXPLAINATION
//
// A simply script to drop in any dir to display next prev buttons and current image for all your images in that dir with extentions you allow
// Uses id parameter to know what image to show next else it will show first image
// Also a number list at bottom page to go to any image, alt text displays image name

// change the colours in the styles in the html body






//which dir
$d = dir(".");

//read thru and
while (false !== ($entry = $d->read())) {
//allow extensions here
//|| preg_match("/(\.bmp$)/i", $entry)
//|| preg_match("/(\.jpeg$)/i", $entry)

if (preg_match("/(\.gif$)/i", $entry) || preg_match("/(\.png$)/i", $entry) || preg_match("/(\.jpg$)/i", $entry)){
$pics[] = $entry;
}

}
$d->close();


//================
//total images count
$numPics = count($pics);



//================
//picture in array to show on this page
$thispic = 0;
if (is_numeric($_GET['id'])){
$thispic = $_GET['id'];
}
$thispicDisplay = $thispic + 1;



//================
//img tag for current image
$thisImage = '<img src="' . $pics[$thispic] . '" alt="' . $pics[$thispic] . '" />';



//======================
// START set thumbnails on or off

//comment this section out if you don't want thumbs to show at all

$showThumbs = 5;//number of thums to show
$thumbsList = '';
$thumburl = '';
if ($_GET['thumb'] == 'yes'){
//read thumb param to url if exists
$thumburl = '&amp;thumb=yes';

for ($i=0;$i<$showThumbs;$i++){
if ($thispic + $i + 1 < $numPics){
$currThumb = $thispic + $i + 1;
$thumbsList .= '<a href="' . $_SERVER['PHP_SELF'] . '?id=' . $currThumb . $thumburl . '" title="' . $pics[$currThumb] . '"><img src="' . $pics[$currThumb] . '" alt="' . $pics[$currThumb] . '" height="100" width="100" border="0" /></a>&nbsp;&nbsp;&nbsp;';
}
}
$onOff ='<a class="thumbs" href="' . $_SERVER['PHP_SELF'] . '?id=' . $thispic . '">Turn Thumbnails Off</a>';
} else {
$onOff ='<a class="thumbs" href="' . $_SERVER['PHP_SELF'] . '?id=' . $thispic . '&amp;thumb=yes">Turn Thumbnails On</a>';
}

// END set thumbnails on or off





//prev button

$prevurl = ' <span class="highlighted">First Picture</span>';
if ($thispic > 0){
$prev = $thispic - 1;
$prevurl = '<a href="' . $_SERVER['PHP_SELF'] . '?id=' . $prev . $thumburl . '" title="' . $pics[$prev] . '">Previous picture</a>';
}




//next button

$nexturl = ' <span class="highlighted">Last Picture</span>';
if ($thispic < ($numPics - 1)){
$next = $thispic + 1;
$nexturl = '<a href="' . $_SERVER['PHP_SELF'] . '?id=' . $next . $thumburl . '" title="' . $pics[$next] .'">Next picture</a>';
}



//=======================
// string of all pics url's
$urlarray = '';
for ($i=0;$i<count($pics);$i++){
//highlign pic you are on
$j = $i + 1;

if ($i != $thispic){

$urlarray .= '<a href="' . $_SERVER['PHP_SELF'] . '?id=' . $i . $thumburl .'" title="' . $pics[$i] . '">' . $j .'</a> ';
} else {
$urlarray .= ' <span class="highlighted">' . $j . '</span> ';
}

$name = substr($pics[$thispic], 0, strrpos($pics[$thispic], '.'));

strrpos (http://us.php.net/manual/en/function.strrpos.php)($pics[$thispic], '.') finds the first dot in the filename starting from the end (i.e., the last dot). substr (http://us.php.net/manual/en/function.substr.php)($pics[$thispic], 0, strrpos($pics[$thispic], '.')) takes the segment of the string from the beginning through the character just before the dot.

So I can safely delete that?

Huh? I didn't tell you to delete anything; that line of code will find the name in "name.ext" and assign it to name. Put it in your code and output name rather than $pics[$thispic] (unless you want the URL).
