thanks erwin. i actually do go that route before reading your post...and it
helped. i have an application class that holds path information...the path
to the security image was wrong. it's all good now.
thanks again,
me

| Hi,
|
| I am too lazy to check your whole script, but you should try to get the
| error.
| This can be done in several ways:
|
| 1) Look in your errorlog
| 2) Call get.security.image.php directly, but change the content-type to
| "text/html".
| Of course this will return a load of crap on succes, because the imagefile
| is not ment to be displayed as text, but you also see the errors.
|
| Good luck,
|

| Erwin Moller
