Giles,
I was attracted to Zenfolio simply by the fact that I could download all my galleries and save full size images. With SmugMug I found the only way to download complete backups, was to save one image at a time, too many of them, use the free applets, one in beta, the other didnt work, see dgrin forums, or pay for an application, or order backup DVDs at $20 a pop. SO I looked else where. Zenfolio will be adding PRO account features to the galleries soon.
Oh, I almost forgot, Zenfolio offer printing through MPIX and EZPRINTS, SmugMug EZPRINTS only, I use alot of metallic paper, SmugMug does not offer that yet.
Still adding images, what do you think.
