I tried it and just modified the path as it is adding the username to
the path but I then get several errors
regarding not opening the stream and also a division by 0:
<?php
$username = $_POST['username'];
//$dir = $path."";
$path = "images/" . $username;
//print "$path<br>";
$i= strlen($path);
//print"$i<br>";
do{$i--;}
while(strpos($path,"/",$i)===false);
//print"$i<br>";
//print substr($path,0,$i);
$path=substr($path,0,$i+1);
$dir=$path;
// Open a known directory, and proceed to read its contents
//if (is_dir($dir)) {
$width=100;
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
//print $dir . $file;
if($file!="." && $file!=".." &&
strtolower(substr($file,-3))=="jpg"){
$size = getimagesize($file);
$height=($size[1]*$width)/$size[0];
echo "<tr><td><img src='$file'width='$width'
height='$height'></td><td><b> <a
href=\"$file\">$file</a></b></td></tr>\n";
}
}
closedir($dh);
}
//}
?>
Gets:
Warning: getimagesize(joomla_logo_black.jpg) [function.getimagesize]:
