Use preview thumbnail included in image when uploading an attachment

With today's large images from camera's and mobile devices, the attach process in XenForo is very slow. Currently XenForo requires the image to be completely uploaded before a thumbnail is created and then displayed. This process can take a lot of time if the user has selected a number of attachments to upload. Often JPG files can be 35MB in size and the entire process of uploading many images can take a minute or more. In contrast uploading to Facebook takes just a second to display a group of preview thumbnails and the upload process is done in the background. How is this done, they use the preview thumbnail contained in the image. I'm hoping that XenForo could implement using the preview thumbnail if contained in the uploaded image so it would be shown immediately as it does in Facebook.
