When i view picturres after they have been transfered to my PC they appear way to large , is there a setting in the camera that will resize them before they are transfered ? Canon Power Shot SX700
I tried reseting it , they gave me a temporary one can't make that one work either , i got a messasge that i may have to contact tech support by phone and have them clear all passwords , should that be my next move ?
This camera is new to me so I am trying to learn all the functions . I can send pictures to my Gateway account via wifi wireless from home but when I'm away it won't work . It must have to be setup to do that  and I don't know how , I contacted Canon...
How can i view my posts and comments , edsr1940
