I am having trouble trying  to change baseball player photos from the names beginning with their first to their last with some of them having the team name and year after them.
 For example:   some have just :   Adam_Kennedy.jpg  Some have:    Adam_Kennedy_LAA.jpg     Some have:  Adam_Kennedy_LAA_2010-2011.jpg
 I want to cahnge them all to :    Kennedy_Adam.jpg    AND    Kennedy_Adam_LAA.jpg    AND  Kennedy_Adam_LAA_2010-2011.jpg.In that order.
How do I go about doing this and can the whole folder with the different type jpg's be done all at the same time.
                                                         Thanks, Mike Hennelly
