str_replace Question That Seems REALLY Familiar

[Digital Jedi]

It's 5:30 in the morning. I slept for about three hours in my daughter's bed making sure she stopped jumping up like a prairie dog and yelling at the night light. (Don't ask. It's something she does. On school nights.) So I'm not sure why my plugin isn't working.

PHP Code:

$picturebitLink = '<a href=\"album.php?$session[sessionurl]albumid=$albuminfo[albumid]&amp;pictureid=$picture[pictureid]\">'; 
$hsLink = $vbulletin->templatecache['highslide_album_link']; 
$vbulletin->templatecache['album_picturebit'] = str_replace($picturebitLink, $hsLink, $vbulletin->templatecache['album_picturebit']); 


I have this dim recollection that I ran into this issue once before way back when Boofoo was still with us. I think Superman or BoP said it had to do with the ? but couldn't understand why. Anyone run into this issue before? I'm going to sleep. Wake me when you've wrote my plugin for me...zzzzzzzzzzzzzzzzzzzzzzzzzzzzz.....
