With no SD Card, how do we flash ROMs and stuff like that?! topic

With all rumors pointing to no sd card on the S6 how do you flash ROMs?? I ask this bc then everything (pics, app/data, nandroids, flashables, etc.) will all have to be stored on the phone's internal sd card. So when you clean wipe your phone for a fresh install wouldn't everything just be deleted, including the ROM you were gonna flash lol?!

All of my previous phones have had sd cards so I'm inexperienced when it comes to no sd card!
