Okay, so I am an Aperture user. I want to keep my photos backed up online somewhere, but would prefer not to pay for the service. I am not a paid photographer, so it's not like I am taking a tiny profit dip by paying for storage. Anyway, I know the usual Shutterfly/Snapfish options both offer unlimited full-res storage. Is one better than the other...even as far as Aperture is concerned? I would like the storage process to be as seamless as possible (ie. perform the upload through Aperture, rather than opening browser and uploading manually). Anyone have any input?
