Salve a tutti
Scusate il post forse gia trattato ma avrei bisogno di inserire un valore nella mia pagina di Upload e il codice php nn lo conosco tanto bene!

Attualmente carico le immagini sul server facendo un resize ad un valore impostato (a scelta)

Noto che comunque, facendo il resize delle immagini a 550x413 risulti ancora abbastanza pesante...

Adesso pensavo di poter abbassare la qualità della stessa tipo all'80% ma nn so come inserire questo passaggio nello script e cercavo aiuto da voi!

Posto il codice e ringrazio anticipatamente!

codice:
<?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>
<?php
// upload the file
if ((isset($_POST["submitted_form"])) && ($_POST["submitted_form"] == "image_upload_form")) {
	
	// file needs to be jpg,gif,bmp,x-png and 4 MB max
	if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" || $_FILES["image_upload_box"]["type"] == "image/gif" || $_FILES["image_upload_box"]["type"] == "image/x-png") && ($_FILES["image_upload_box"]["size"] < 4000000))
	{
		
  
		// some settings
		$max_upload_width = 550;
		$max_upload_height = 413;

//		$max_upload_width = 2592;
//		$max_upload_height = 1944;
		$path=$_POST['path'];
//print $path;

		  
		// if user chosed properly then scale down the image according to user preferances
		if(isset($_REQUEST['max_width_box']) and $_REQUEST['max_width_box']!='' and $_REQUEST['max_width_box']<=$max_upload_width){
			$max_upload_width = $_REQUEST['max_width_box'];
		}    
		if(isset($_REQUEST['max_height_box']) and $_REQUEST['max_height_box']!='' and $_REQUEST['max_height_box']<=$max_upload_height){
			$max_upload_height = $_REQUEST['max_height_box'];
		}	

		
		// if uploaded image was JPG/JPEG
		if($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg"){	
			$image_source = imagecreatefromjpeg($_FILES["image_upload_box"]["tmp_name"]);
		}		
		// if uploaded image was GIF
		if($_FILES["image_upload_box"]["type"] == "image/gif"){	
			$image_source = imagecreatefromgif($_FILES["image_upload_box"]["tmp_name"]);
		}	
		// BMP doesn't seem to be supported so remove it form above image type test (reject bmps)	
		// if uploaded image was BMP
		if($_FILES["image_upload_box"]["type"] == "image/bmp"){	
			$image_source = imagecreatefromwbmp($_FILES["image_upload_box"]["tmp_name"]);
		}			
		// if uploaded image was PNG
		if($_FILES["image_upload_box"]["type"] == "image/x-png"){
			$image_source = imagecreatefrompng($_FILES["image_upload_box"]["tmp_name"]);
		}
		
		// Cartella dove caricare i files
		$remote_file = "images/stories/$path/".$_FILES["image_upload_box"]["name"];
		imagejpeg($image_source,$remote_file,100);
		chmod($remote_file,0644);
	//print $remote_file;
	

		// get width and height of original image
		list($image_width, $image_height) = getimagesize($remote_file);
	
		if($image_width>$max_upload_width || $image_height >$max_upload_height){
			$proportions = $image_width/$image_height;
			
			if($image_width>$image_height){
				$new_width = $max_upload_width;
				$new_height = round($max_upload_width/$proportions);
			}		
			else{
				$new_height = $max_upload_height;
				$new_width = round($max_upload_height*$proportions);
			}		
			
			
			$new_image = imagecreatetruecolor($new_width , $new_height);
			$image_source = imagecreatefromjpeg($remote_file);
			
			imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height);
			imagejpeg($new_image,$remote_file,100);
			
			imagedestroy($new_image);
		}
		
		imagedestroy($image_source);
		
		
		header("Location: submit2.php?upload_message=image uploaded&upload_message_type=success&show_image=".$_FILES["image_upload_box"]["name"]);
		exit;
	}
	else{
		header("Location: submit2.php?upload_message=make sure the file is jpg, gif or png and that is smaller than 4MB&upload_message_type=error");
		exit;
	}
}

      Notes:

  The image will not be resized to this exact size; it will be scalled down so that neider width or height is larger than specified.

  When uploading this script make sure you have a directory called &quot;image_files&quot; next to it and make that directory writable, permissions 777.

  After you uploaded images and made tests on our server please delete all uploaded images  :)

<?php if(isset($_REQUEST['show_image']) and $_REQUEST['show_image']!=''){?>



Quale immagine ho caricato
</p>
<?php }?>

</body>
</html>
Ps: Alla voce "che immagine ho caricato, sarebbe possibile recuperare l'immagine appena caricata..
Ho provato cosi ma senza risultato

codice:
<?php if(isset($_REQUEST['show_image']) and $_REQUEST['show_image']!=''){?>
