Hi,

The problem is that you don't need to pick the thumbnail after snapping it, as the "snap thumbnail" option automatically puts the thumbnail in the correct directory. When you select that thumbnail with the pick thumbnail, it tries to move the image from that directory to the same directory which probably causes the error.

I'll make sure the error is fixed but as for the snap thumbnail option, you don't need to pick it after snapping it.
