* Creates thumbnail for an image.
* Will create a thumbnail in cropped square, or a resized version of the orginal depening on $thumb_type
* Currently outputs thumbnail into $output_directory only
* If used with $check_existing, you can check to see if your thumbnail exists in your output directory before you create a new thumb. Very useful when you want this to 'monitor' a directory for new files to thumbnail
*
* @param string $img source image you wnat to thumbnail
* @param string $output_dir the directory where you want your thumbnail to be placed
* @param boolean $check_existing check to see if the thumnail already exists in your output dir, if it does, it will skip making a thumbnail
* @param string $thumb_type specifies the type of thumbnail you want to create. currently supports a cropped square version, or a small resized versino of the source $img
* @param int $dst_width the width you want for your new thumbnail
* @param int $dst_height the height you want for your new thumbnail
* @param double $crop_factor the crop factor used from the original picture. Higher = less crop from the orig, Lower = more crop. 0.5 seems to be the best
* @param int $quality the quality you want for you thumbnail.
*
* @return boolean TRUE if new image creation was successful, FALSE if not
