It is good to look at this code (not sure if Mozilla under Linux didn't like
the javascript, but glad others could see it).
You are right in that there are no blob files in it.. However, i wasn't
starting from that file. Rather from a phplib class that was posted right here:

I shouldn't need to use this command should I?
http://php.net/manual/en/function.addcslashes.php
I've used stripslashes before effectively in other pieces of code..

Ok.. I've modified this..

Must admit that I've been thrown by this one.. I've got no idea what's up with
this..

You are right.. I had commented this out because I was getting an error that
the header was already loaded.. I figured since I saw that in the database as
well that it had been inserted and was now redundant.

So you want the new code to look like this (for what is now
http://pgs.ca/WLP/profiles/getimage-simple.php3):
mysql_connect($DBHOST, $DBUSER, $DBPASS);
mysql_select_db($DATABASE);
$resultset = mysql_query($query);
header("Content-type: image/jpeg");
$query = "SELECT image FROM ztpv_images WHERE imageID = $imageID";
$resultset = mysql_query($query);
print(base64_decode(mysql_result($resultset, 0, "Image")));
Hadn't done the following before:

Seems like taking out the add/remove slashes has elminated it from here:
[mike@office admin]$ wget -s
http://pgs.ca/WLP/profiles/getimage-simple.php3?imageID=20
--01:47:53-- http://pgs.ca:80/WLP/profiles/getimage-simple.php3?imageID=20
=> `getimage-simple.php3?imageID=20'

01:47:53 (38.18 KB/s) - `getimage-simple.php3?imageID=20' saved [7468]
The image size is about right.. I thought it was 7440 (according to netscape
when I uploaded it).. Not sure why it would be bigger..
