Pushing this topic. I noticed a problem downloading the original binaries of images in the albums on Facebook. I have the "Prefer HD quality" option selected in the Facebook settings. But still, it downloads the "_n.jpg" files instead of the "_o.jpg" files.

To manually download the original image as it was originally uploaded to Facebook, bring up an image from an album. Then on the bottom of the image, select "Options" and then "Download".

Thanks!
