Storing photos on the cloud

Hi All,

I've an iPhone5 - 16GB and it's just about to run out of space.

I've about 3 gig of photos what I'd like to keep. I know I could move thme to my PC.. But i'm no the move now and not back at my PC for a while.

I see Apple give you 5Gig free on the cloud. Is there anyway I can move the photo's to it and free up some space ?

What can I store on the cloud ? and how can I move stuff there ?

thanks.
