I have spent quite a bit of time trying to figure out this error with no luck. Here is the error message I am getting:
Warning: getimagesize(http://www.planetdouglas.com/images/userphotos/birdgirl.jpg): failed to open stream: Permission denied in /home/***/system/lib-custom.php on line 365
Warning: Division by zero in /home/***/system/lib-custom.php on line 379
I have changed the name of my database (to protect the innocent) to ***. The problem is with the random member block which randomly displays a random members image.
If anyone has any ideas I would appreciate your help.
Thank you.

Here is the code from my lib-custom.php file beginning at line 363.
$uphoto_url = "{$_CONF['site_url']}/images/userphotos/$uinfo[photo]";
$uphoto_size = getimagesize($uphoto_url); // returns an array
$uphoto_width = $uphoto_size[0];
$uphoto_height = $uphoto_size[1];
// determine which dimension is larger
if ($uphoto_height > $uphoto_width) {
$largest = "uphoto_height";
} elseif ($uphoto_width > $uphoto_height) {
$largest = "uphoto_width";
} else { // they are equal
$largest = "uphoto_height";
}
// determines the percentage of shrinkage we'll need to use
$shrink_amount = ($image_max_bounds*100) / $$largest;
$shrink_amount = ceil($shrink_amount);
if ($shrink_amount > 99) { // it's already smaller - don't change it
$iwidth = $uphoto_width;
$iheight = $uphoto_height;
} else { // determine the new image size after shrinking
$iwidth = ceil($uphoto_width * ($shrink_amount / 100));
$iheight = ceil($uphoto_height * ($shrink_amount / 100));
}

What version of PHP are you using?
I am using 4.3.8
try changing $$largest to $largest.
I thought about that myself but I have been told by a php guy that that is not the problem. I will give it a try anyway and see what happens.
I think it is a logic problem with resizing the images. I suspect the images that are causing the errors are all the same size. Thank you for the help.

Here is the whole thing:

// set the preferred maximum size (will fit within a square this size)
$image_max_bounds = "100";
$pathtoimages = $_CONF['path_html'] . 'images/userphotos';
// Do database query
$sql = "SELECT * FROM gl_users WHERE photo <> 'NULL' && (photo <> '') ORDER BY RAND() LIMIT 1";
$result = mysql_query($sql);
$uinfo = mysql_fetch_array($result);
// Get and size Picture

Looks like it's failing on users with a space in their name. Place this before // Get and size Picture...
$user_photo = str_replace(" ","%20",$uinfo[photo]);
and replace $uinfo[photo] with $user_photo. Works fine on my site after that.
