in my php.ini Maximum size of POST data that PHP will accept. is post_max_size = 20M is these are ok ? or should i change to something else ?

my upload_max_filesize in php.ini is 200M is it ok ?

i am uploading image to s3 server and by php i am making a copy of that image on server , if i upload an image of 2.3 mb than the width of image is not coming but if i upload less size image like 26kb than it is showing the width of image so it is able to create the copy . here is my code of php : $s3 = new S3(awsAccessKey, awsSecretKey); $thumbId = uniqid(); $thumbId .= ".jpg"; $img = ''; if($imgType == "image/jpeg"){ $img = imagecreatefromjpeg($sourceUrl); }else if($imgType == "image/png"){ $img = imagecreatefrompng($sourceUrl); }else if($imgType == "image/gif"){ $img = imagecreatefromgif($sourceUrl); }else{ $img = imagejpeg($sourceUrl); } echo $width = imagesx( $img ); echo $height = imagesy( $img ); please tell me what is the problem with size of image.. regards rahul

^^^ you need to turn that setting ON. ok thanks its working regards rahul
