If that's the case here, you could be attempting to load images which cannot be found.

I thought of that.

# further up in the code:
my $dir = $ENV{HOME} . "/www/pix/gallery";
# this points to the only place we should be loading 
# images from. 
|
| Loop through the directory and populate all the valid
| file names into an array
my $image=sprintf( "%s/%s",$dir,$imageStack[rand($top)]);
# that picks a single name out of the list and prepends
# the full path of the gallery directory to the name.

At one point in my development of this script I did actually have a chdir to the gallery and eliminated it thinking there was some funky-delic permissioning issue going on with the server itself. The random selection code works. I'm just getting those nasty premature header ending errors.
