Create an idea book of photos you want to share, and add your spouse, builder, and architect as collaborators. We do it with our clients all the time.

Ellsworth-Hallett is correct! The best way to do this is to use the collaboration feature on an ideabook. Then your photos are all in one place instead of spread out in several emails.

The houzz. com ideabooks were very helpful to me & my "team" during a recent build. I was 900 miles away 90% of the time. You can bring your builder, architect, designer & whomever else you want to share with in on your ideas.
One thing you might want to keep in mind is that every time you add a pic to an idea book you're using as a collaborative tool, all of your collaborators get an email. I found that out only after my builder let me know he'd gotten 10 emails one day. EEK. Thankfully, it's easy to add/subtract collaborators.......good luck!!!
