The script works fine when I test it on a stand alone page. I'm just
not sure how to include with the "rest" of the site.

Probably nothing really. When it complains about headers already
being sent is the line number the same as your header() line below?
If so, that means you're outputting something back to the browser
prior to that line.
I'd make sure you don't have any white space before your initial
opening <?php tag and I'd also look at "Some query" to see if it's
spitting out an error or some sort...

Hello Everyone,
I wrote a GD function that resizes some images and displays them as
thumbnails. When I put the function in the index.php page I receive
an error Warning: Headers have already been sent... then it shows a
bunch of binary. I do not want re-save the file, I just want resize
and show it. What am I doing wrong here? Any help would be great.
