format change of a picture

[colake]

I have a page where a user can see information about a other user. Sometimes have a user a picture on that page. The sizes of the pictures are verry diverent.

I have found a code where the size is changed in. But I don't get the picture on the page. The url to the picture is stored in a mysqldatabase.

Can someone help me?

This is the code:

 <img src=
        <?php 
		if ($i[pic]) 
		{
	    	if (!$width)
		 	{
		 		$thumbX = 100;
		 	}
	    	else 
			{
				$thumbX = $width;
			}

	$src = ImageCreateFromJPEG($i[pic]);
	$thumbY = ($thumbX/ImageSX($src)) * ImageSY($src);

	$thumb = ImageCreate($thumbX+0,$thumbY+0);
	ImageCopyResized($thumb,$src,0,0,0,0,$thumbX,$thumbY,ImageSX($src),ImageSY($src));


	ImageJPEG ($thumb);
	}
	else {print "foto niet gevonden";}
