Not quite sure what you mean, but something like this?
It puts all the extensions from the array in front of the file path, and if it exists, it outputs the image.

$extensions_to_check = array('jpg','png','gif','jpeg');
$dir = '/path/to/dir/';
$file_name = 'wallpaper_something';

foreach($extensions_to_check as $ext) {
   $path = $dir . $file_name . $ext;
   if (file_exists($path)) {
      echo('<img src=\'' . $path . '\' />');
   }
}
