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.
