iPhone storage full of photos, offload to iCloud storage?

No, iCloud is a syncing service, not an archiving service. However, you can sync your photos to iCloud, then enable Optimize Storage on your iPhone and it will compress the photos on your phone to about 1/4 size, reducing their resolution, but still keep the full resolution images in iCloud.

IN addition to this, when you select the compressed photo to view it on your phone AND you are connected to the internet, it will download the FULL resolution photo for you to enjoy. :)

Good point; thanks for mentioning it.
