code I am using:

//Upload Photos
if(isset($_POST['submit']))
{
if (isset ($_FILES['pictures']))
	{
		ini_set("memory_limit","12M");						                       
		$i = 0;
		//Looping through elements of array
foreach ($_FILES["pictures"]["error"] as $key => $error) 
{
	//Checking file extensions and photo size	
	if ((($_FILES['pictures']['type'][$i] == "image/gif")
	|| ($_FILES['pictures']['type'][$i] == "image/jpeg")
	|| ($_FILES['pictures']['type'][$i] 
                =="image/pjpeg"))&& ($_FILES['pictures']['size'][$i] 
	< 2500000))											
                {
// check if user actually put something in the file input field.

Create a file named .htaccess in your web root with this to make sure your server isn't limiting file upload size:

upload_max_filesize
php_value post_max_size 30M
php_value upload_max_filesize 10M

 

Or modify PHP.ini and place those values in yourself.

 

Also, note 2.5MBs is larger than 2,500,000 bytes. 1024x2500 = 2,560,000..
