Thanks for pointing this out. It would seem that you have to use SmugMug, have all of your photos on that system, and give access to people to that account and they do the cropping on line, and then order prints...Is that right?
So what do you do for people reviewing a CD or DVD full of photos, off line and not connected to the web? (after all, many folks have slow modem access only, even now, because of living in areas where high speed DSL is simply not available...I could not get high speed DSL mid-way between San Francisco and Silicon Valley, because I was too far from some access point, and that only changed finally about 7 years ago!
You upload to albums, then give clients the password or link to that album, then they order prints. If they order a 17x12 or something strange, then they're prompted to crop, or at least review the default crop provided for them.
As far as off-line, that's a great point, I have no answer for you.. I've never encountered that scenario. I live in a major city, so my workflow for ordering revolves around people having high-speed access. You're right though, for many photographers in rural areas, the online proof / ordering may not work well at all.
