My partner has started an archival project scanning historical family photos. She currently uses Picasa/Google drive, but is bumping up against the upper storage limits. She is looking for the best remote storage option. She's not as concerned with sharing, though eventually she may like to do so, she is mostly interested in being able to access them remotely and cross platform. (She has a macbook, an android phone, and we have PC's at home.) I use imgur myself for basic storage/sharing, but I'm not sure that's the best option for her. Anyone have any thoughts or suggestions?
