I've tried as you suggested and the avatar doesn't appear at all now.
PHP Code:
$url = "<img src=\"$avauri[0]\" $avauri[1] alt=\"$uname\'s Avatar\" title=\"$uname\'s Avatar\" />";
Tried switching [0] and [1] too, but to no avail.
EDIT:, apparently, now this appears as result:
PHP Code:
<img src=" width=" 120"="" height="68" "="" image.php?u="1&dateline=1295958757" alt="Test\'s Avatar" title="Test\'s Avatar"/>
EDIT2: Alright, fixed! It was my bad, it did work in the first place; $avauri[0] returns the url, and $avauri[1] returns width and height. So, it works perfectly now.
Thanks a fortune, kh99!
