$this is only valid in a class member function. I'm not sure which php
gallery script you're using (there are several of them with similar
names), but unless you've created a class with the above information (or
derived your own class from one with the above information public or
protected), it won't work.
But you didn't give enough of your code for us to provide any real help.
A couple of suggestions: First, on your development system, turn on all
error reporting and display the errors. In your php.ini file, you
should have:
error_reporting = E_ALL
display_errors = on
(You should have display_errors = off in your production system for
security reasons).
Second, if you're still having problems, please post enough code so we
can help you.
P.S. Ignore "Pointed Head". He's just a troll who jumps on anyone who
doesn't follow HIS rules of netiquette. There is no requirement here to
use a real name (although many of us do).
