Strange PHP multiple file upload issue - php

Question

Before you asked, I did look at all the similar topics and did not not find the solution to my problem. When I try to upload multiple files, say 4, 3 files are uploaded. I am really sure the loop is correct, but i could be wrong. Self-taught PHP newbie.
The code is as follows:
if(isset($_POST['submit']) && $_POST['submit']=="Upload"){
if(count($_FILES['image_filename']['name']) == 0)
{
$form->seterror("fileupload"," * At least one file required.");
}
if($form->num_errors == 0)
{
$directory="../../images/properties";
$ref='';
//Loop through each file
for($i=0; $i<count($_FILES['image_filename']['name']); $i++)
{
if($_FILES['image_filename']['name'][$i] != "")
{
//Get the temp file path
$filename = $_FILES['image_filename']['name'][$i]; // filename stores the value
$filename = str_replace(" ","_",$filename);// Add _ inplace of blank space in file name, you can remove this line
$filename = stripslashes($filename); // strip file_name of slashes
$filename = str_replace("'","",$filename); //remove quotes
$filesize = $_FILES['image_filename']['size'][$i];
$filetype = $_FILES['image_filename']['type'][$i];
$filetemp = $_FILES['image_filename']['tmp_name'][$i];
//echo $filename.'<br>';
$filework->file_upload($_FILES['image_filename']['name'][$i],$directory,$_FILES['image_filename']['tmp_name'][$i]); // this is my File upload class
$ref=$_FILES['image_filename']['name'][$i];
if($countImg == 0) {
if($i==0) {
$main='1';
} else {
$main='0';
}
} else {
$main='0';
}
$q="INSERT INTO property_images(property_id,image_filename,image_reference,main_image)".
" VALUES (".$_GET['pid'].",'".$_FILES['image_filename']['name'][$i]."','".$ref."','".$main."')";
//echo $q.'<br>';
$database->query($q) or die(mysql_error());
$x++;
}
}
}
}
[/code]

Isn't the loop skipping the last file?
Try changing this:
for($i=0; $i<count($_FILES['image_filename']['name']); $i++)
to:
for($i=0; $i<=count($_FILES['image_filename']['name']); $i++)
