UPDATE: I have almost solved this problem, please see Jquery form no submission to IE7 and IE8 i just need to sort ot ie7 and ie8,
I have been using THIS plugin to upload files as an email attachment, i have gotten it to the point where it actually works, the only problem is it currently uses this to submit:
jQuery.ajax({
    beforeSend: function() {
        status.empty();
        var percentVal = '0%';
        bar.css("width", percentVal)
        percent.html(percentVal);
    },
    uploadProgress: function(event, position, total, percentComplete) {
        var percentVal = percentComplete + '%';
        bar.css("width", percentVal)
        percent.html(percentVal);
        //console.log(percentVal, position, total);
    },
    complete: function(xhr) {
        status.html(xhr.responseText);
    }
}); 
And the form i need to add it to, uses this to submit:
jQuery.ajax({
        type: "POST",
        url: "mail.php",
        dataType: "json",
        data: {parameters: jsonData}
    });
How would i make the plugin work with my form of submission?
Here's the JSFIDDLE for the current working upload form.
and then the form i need to combine the working one with JSFIDDLE (i have shortened it to only the upload fields, but there is a bunch of other information)
Also here's the php send function:
<?php
    function printMember($member) {
        foreach($member as $key=>$value) {
            //Fill the aux string first
            $str.= "$key : $value <br />";
        }
        //string that will be added to $msg variable inside the loop
        return $str;
    }
    $json = $_POST['parameters'];
    $json_string = stripslashes($json);
    $data = json_decode($json_string, true);
    $depCount = count($data["dependants"]);
    $msg .= "<h2>Main member data:</h2>";
    $msg .= printMember($data["mainmember"]);
    $msg .= "<h2>There are $depCount Dependants</h2>";
    foreach ($data["dependants"] as $index => $dependant) {
       $msg .= "<h2>Dependant $index</h2>";
       $msg .= printMember($dependant);
    }
    $strTo = "dawid@jamfactory.co.za";
    $strSubject = "Image Testing";
    $strMessage = nl2br($msg);
    //*** Uniqid Session ***//
    $strSid = md5(uniqid(time()));
    $strHeader = "";
    $strHeader .= "From: Dawid<test@testme.co.za>\nReply-To:test@testme.co.za";
    $strHeader .= "MIME-Version: 1.0\n";
    $strHeader .= "Content-Type: multipart/mixed; boundary=\"".$strSid."\"\n\n";
    $strHeader .= "This is a multi-part message in MIME format.\n";
    $strHeader .= "--".$strSid."\n";
    $strHeader .= "Content-type: text/html; charset=utf-8\n";
    $strHeader .= "Content-Transfer-Encoding: 7bit\n\n";
    $strHeader .= $strMessage."\n\n";
    //*** Attachment ***//
    $count = 0;
    foreach($_FILES['myfile']['name'] as $filename)
    {
        $temp = $_FILES['myfile']['tmp_name'][$count];
        $strFilesName = $filename;
        $strContent = chunk_split(base64_encode(file_get_contents($temp))); 
        $strHeader .= "--".$strSid."\n";
        $strHeader .= "Content-Type: application/octet-stream; name=\"".$strFilesName."\"\n"; 
        $strHeader .= "Content-Transfer-Encoding: base64\n";
        $strHeader .= "Content-Disposition: attachment; filename=\"".$strFilesName."\"\n\n";
        $strHeader .= $strContent."\n\n";
        $count++;
    }
    $flgSend = @mail($strTo,$strSubject,null,$strHeader);  // @ = No Show Error //
    if($flgSend)
    {
        echo "Mail send completed.";
    }
    else
    {
        echo "Cannot send mail.";
    }
?>
If anyone doesn't fully understand the question, I will try here to even further explain it:
I have duplicate-able fields that on submit the information gets put into a JSON array and then gets parsed to an email by PHP, what i was trying to do is have a file field where images get uploaded and sent with the email, but after researching a lot on the web I found that this is not possible with ajax so I found THIS plugin that actually works and now i am just trying to combine it with my original form
