Confused!!

I keep trying to put my photos in, but it keeps saying I need to make an account, but there is NO WHERE on this APP to sign up for an account, it just has whee to put your user name & password, but it doesnt tell you where to sign up to get an account!! Can someone tell me where to go?? I paid for this APP, will be very disappointed if I cant get an account, will rate this better if someone can tell me, where to go get an account, cause it sure isnt on this APP, I have pressed every button there is!!
