[cin772001]

Hi, I am hang an impossible time trying to post a photo for the Galaxy s5 photo contests!! I have asked and received replies and for some unknown reason I'm having a brain blockage on how the heck to figure out the process?? I am sorry for being such a pain asking over and over again! Could someone PLEASE walk me through the process? I have no clue why this is so hard for me to understand?? Thank you so very very much! It would be extremely appreciated!! Thanks again and again, Cindy
