Problema con plupload

[ainvar57]

Como no cabía sigo aquí:

Pongo también el código javascript de inicialización de plupload.

Código HTML:

<script type="text/javascript">
// Convert divs to queue widgets when the DOM is ready
var subidosval = $('#subidos').val();

$(function() {
	$("#uploader").pluploadQueue({
		// General settings
		runtimes : 'html5,flash',
		url : 'includes/subemasfotos.php?id=' + <?php echo $_GET['id']; ?>,
		max_file_size : '10000mb',
		max_file_count: 50, // user can add no more then 50 files at a time
		chunk_size : '10mb',
		unique_names : false,
		multiple_queues : false,
		rename: false,
		// Sort files
		sortable: true,
		// Specify what files to browse for
		filters : [
			{title : "Image files", extensions : "jpg,jpeg,gif,png"}
		],
		// Flash settings
		flash_swf_url : 'js/plupload.flash.swf',
		multipart : true,
		multipart_params : {
    	    'subidos' : subidosval
	    }
	});
		// Client side form validation
	$('#masfotos').submit(function(e) {
        var uploader = $('#uploader').plupload('getUploader');

        // Files in queue upload them first
        if (uploader.files.length > 0) {
            // When all files are uploaded submit form
            uploader.bind('UploadComplete', function() {
                if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
                    $('form')[0].submit();
                }
            });
                
            uploader.start();
        } else
            alert('Debe subir un archivo por lo menos.');

        return false;
    });
});
</script> 

y el html

Código HTML:

<form action="" method="post" name="masfotos" id="masfotos">
<div id="uploader"><p>You browser doesn't have Flash or HTML5 support.</p></div>
<input name="subidos" type="hidden" id="subidos" value="FilesUp">
</form>
