Sorry I didn't include more details. Here is the bulk of show_ipx.pl:

my $sth = $dbh->prepare(qq(SELECT tripdata, tripmimetype FROM vacation
+_files WHERE id=?));
$sth->execute($id);
$sth->bind_columns(\$tripdata, \$tripmimetype);
$sth->fetch();
$sth->finish();
$dbh->disconnect;
$tripmimetype = ($tripmimetype eq "application/octet-stream") ? 'appli
+cation/x-ipix' : $tripmimetype;
print "Content-type: $tripmimetype\n";
print $tripdata;
exit;

I checked and is printing out the correct mime type.
When I insert it into the database it gets the mime type of application/octet-stream for some reason.
Thats why I'm changing it when pulling it back out.

Thanks again
