What Roy said.... But just change the setting on your phone down so you wont have to edit all the time. It does not have to be 600pxs wide, our software will take them down automatically to a determined sized. You can also take a screen shot of your pics that are on your phone and they will post fine.
However, there is no need to take pics on the default Giamungus default settings of cell phone. The only reason you really need those sizes is to make big posters. And you still don't need 4000. Half of that is plenty, for posters, but if you want a poster size print out, just change you setting for that photo shoot and change it back.
Those huge settings run up storage on your phone and computer, and its done for a purpose. I won't get into the weeds on that one.
