Re: One more GD ? -- filename

[Craig Hoffman <choffman@xxxxxxxxxx>]

I believe the problem is somewhere in the GD script.  Because when I 
view the source it shows an empty variable.  I should at least see the 
name of variable in the source.  Any ideas?
<img src='include/function_gd.php?route_photo='..'' height='x' 
width='x' align='center' id='image'>
