[SOLVED] image problem

[asmith]

hey guys

on the user part of my site , i show the user an image selected from a lot of images on the site by its url .

the problem i have is some of the images are JPG and some are GIF . but i only know the name of the image . so when i am creating the link for the user  :

 

http://www.example.com/img/img56.  ???

 

i don't know what is the image type to complete the link for the user. 

 

 

any idea ?

how can i get that type fast and safe ?

thanks

2 ways to do this

either

A) store the extensions

B) do something like this

<?php
$imgname = "myimage";
$img_ext = array("jpg", "JPG", "gif", "GIF", "png", "PNG");
$i = 0;
while(!isset($imgset)){
   if(is_file($imgname.".".$img_ext[$i])){
      echo "<img src=\"".$imgname.".".$img_ext[$i]\" alt=\"\" />";
       $imgset = "yes";
   }
   $i++;
}
unset($imgset);
?>

A more universal solution attempts to match that extension to a pool of em.

I always love the unconventional while loop solutions that don't loop an array thats why we have while and that why we have for loops
