Valum file upload - Works in Chrome but not IE, Image img = Image.FromStream(Request.InputStream)

I'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream.

The following line of code is failing in IE 8 but is confirmed to work in Chrome.

using (Image imgInput = Image.FromStream(Request.InputStream))

The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).

Anyone have any ideas or are there more details I can include? The same image is able to be used in Chrome and is uploaded appropriately.

Turns out that there is not an input stream in the Request when using IE as your browser. Ended up fixing the code by pulling it out of the Files array like this:

if (String.IsNullOrEmpty(Request["qqfile"]))
{ 
    //This works with IE
    HttpPostedFileBase httpPostedFileBase = Request.Files[0] as HttpPostedFileBase;
    byte[] newImageByteArray = GetByteArrayForResizedImage(350, httpPostedFileBase.InputStream);
    byte[] thumbnailByteArray = GetByteArrayForResizedImage(150, httpPostedFileBase.InputStream);

    //Do stuff here

    return Json(new { success = true }, "text/html");
}
else
{
    byte[] newImageByteArray = GetByteArrayForResizedImage(350, Request.InputStream);
    byte[] thumbnailByteArray = GetByteArrayForResizedImage(150, Request.InputStream);

    //Do stuff here

    return Json(new { success = true }, "application/json");
}
