Steve, I've got your point.

But I meant something different.

It is okay to use both

PHP Code:

<?php 

$cmtx_box .= "<img src='http://www.gravatar.com/avatar/" . md5(strtolower(trim($email))) . ".png?s=71" . $gravatar_parameter . "' alt='Gravatar' title='Gravatar'/>";

You could check whether $old_picture has a value before trying to use it:

PHP Code:

<?php 

$old_picture = $row['picture'];



if (!empty($old_picture)) {

$cmtx_box .= '<img src="' . MM_UPLOADPATH . $old_picture . '" alt="Profile Picture" />'; // User has a profile picture so display it

} else {

$cmtx_box .= "<img src='http://www.gravatar.com/avatar/" . md5(strtolower(trim($email))) . ".png?s=71" . $gravatar_parameter . "' alt='Gravatar' title='Gravatar'/>"; // User does not have a profile picture so display Gravatar

}

Yeah...

This works.

Cheers!
