When I load a pic to use on a thread it goes into the file as a thumbnail. The problem is that all the thumbnails are squares with a question mark in the square. I cant tell what the pic is of as I dont name each and every pic before up loading. Is there a switch that I can toggle and actually see the thumbnails hense knowing what the thumbnail is of? Also for some reason I cant delete any pics from that file? Or am Missing something?

Thanks for any direction or advice in advance.
