	Purpose:  This script can be used to resize one or more images.  It will save the file to a directory and output the path to that directory which you 

			  can display or write to a databse. 

	

	TO USE, SET: 

		$filename = image to be resized

		$newfilename = added to filename to for each use to keep from overwriting images created example thumbnail_$filename is how it will be saved.

		$path = where the image should be stored and accessed. 

		$newwidth = resized width could be larger or smaller

		$newheight = resized height could be larger or smaller

		

	SAMPLE OF FUNCTION: makeimage('image.jpg','fullimage_','imgs/',250,250)

	

	Include the file containing the function in your document and simply call the function with the correct parameters and your image will be resized.

//IMAGE RESIZE FUNCTION FOLLOW ABOVE DIRECTIONS

	$image_type = strstr($filename, '.');



	//SWITCHES THE IMAGE CREATE FUNCTION BASED ON FILE EXTENSION

		switch($image_type) {

			case '.jpg':

				$source = imagecreatefromjpeg($filename);

	//CREATES THE NAME OF THE SAVED FILE

	$file = $newfilename . $filename;

	

	//CREATES THE PATH TO THE SAVED FILE

	$fullpath = $path . $file;



	//FINDS SIZE OF THE OLD FILE

	list($width, $height) = getimagesize($filename);

	$thumb = imagecreatetruecolor($newwidth, $newheight);



	//RESIZES OLD IMAGE TO NEW SIZES

	imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);



	//SAVES IMAGE AND SETS QUALITY || NUMERICAL VALUE = QUALITY ON SCALE OF 1-100

	imagejpeg($thumb, $fullpath, 60);



	//CREATING FILENAME TO WRITE TO DATABSE

	$filepath = $fullpath;

	

	//RETURNS FULL FILEPATH OF IMAGE ENDS FUNCTION

shArk:1. vypsalo ti to nějakou chybovou hlášku? pokud ne napiš na uplny začátek scriptu
error_reporting(E_ALL);
mělo by to začít vypisovat chybové hlášky, i varování atd.
