    show another image if image not found

    Hi
    ive created a webpage which gets images from a database. I need to tell it to to display another image (which says no image available) if an image is not found. How would I do this????

    Your suggestions would be very much appreciated

    Can we see the code to see how you pull the images?

    if your pulling images from the DB then it wont return any rows when looking, so use mysql_num_rows() to check the number of rows is 1 or more, otherwise redirect or load your default fall back image.

    <TABLE CELLSPACING=1 CELLPADDING=4 bgcolor="#FFFFFF" WIDTH=666 BORDER=0>

    <?php

        
    #connect to MySQL
        
    $connpg_connect"host=pgdbs user=wwwuser dbname=dwt password=wwwuser")
                         or die( 
    "Err:Conn" );

             
        
    $query "SELECT * FROM shoes";
          
    $result pg_Exec ($conn$query);
          
          
    $rows pg_Numrows($result);

          if ((!
    $result) || ($rows 1)) {
                      echo 
    "<H1>ERROR - no rows returned</H1><P>";
                      exit;  
    //exit the script
                      
    }

         for (
    $i=0$i $rows$i++)
        {
        
    $code pg_result($result,$i,"code");        
        
    $colour pg_result($result,$i,"colour");
            
    $name pg_result($result,$i,"name");
        
    $sex pg_result($result,$i,"sex");
        
    $min_size pg_result($result,$i,"min_size");
        
    $max_size pg_result($result,$i,"max_size");
        
    $price pg_result($result,$i,"price");

    try replacing:
    PHP Code:
    <IMG src= "<?php echo $image_url ?>" width="100" height="100">
    with something like:
    PHP Code:
    <IMG src= "<?php
    echo ($image_url=="")?"DEFAULT IMAGE URL GOES HERE":$image_url;
    ?>" width="100" height="100">
    you will need to fill in the default image URL and maybe change the empty quotes to something else if your DB using something other than a blank string is no URL is input.
