question about the buying storage option

is the prices only for 1 month, so id have to purchase the same space of storage i need every month?

say i bought 50mb, does that add to the 10mb i already got making it 60mb?

also after the month is up and say i bought 50mb, and using 40mb total of it, do i loose everything that is above the free 10mb's if i dont spend to buy more every month (if thats how it works) and it all just goes lost where if i add it a couple days after a month or a week or whatever all the images uploaded to the gallery making the total of 40mb will be lost? being they all have to be reuploaded? since i didnt add the storage for that month on time?


someone explain it more to me, and how it works

no one is explaining much when it comes to gallery storage do they..

kinda sad really...
