Yes. When cropping an image for a thumbnail, I suggest making the image a square (you can do so in Paint.net by selecting the "Rectangle Select Tool" and clicking the drop down on the rectangle select toolbar and select "Fixed Ratio" and make sure the height and width are equal (doesn't matter what the values are) and in GIMP, by selecting the "Rectangle Select Tool" and going to where it says size and make the height and width values equal). Essentially you'll likely want to capture the head/neck/top of shoulders on the castaway's image, regardless of how big the selection will be, as you'll simply cut/copy it onto a new canvas and resize (typically under "Image" on the topmost toolbar) it to an appropriate size.

As for the borders, I'm not entirely sure, as it was decided by the admins to drop the borders, seeing they really didn't need to be there.
