What's the difference between "post a photo" and "upload a digital photograph"?I can not see where I have used the phrase "post a photo" but please correct me.
The post card goes in the normal snailmail post, US Mail, Royal Mail, Canada Post etc. You do not have to scan. Just put the real name (not say mad viking) and address on it, correct postage stamp plus a message would be nice for the person receiving it so that they know what it is for; then put it in a post box.
The digital photograph would be uploaded onto the thread. I have never done this myself could someone link an easy guide, what about the size of the photo?
I assume you did not buy a camera then. (from the first page of the thread you linked)
To me that suggests that you want people to take a picture of the postcard.
If any kind of camera is involved in this, count me out. I'm happy to send postcards, and if any recipient wants to take a picture of it or scan it, fine. But digital cameras baffle me and I would rather not have to muck around with one.
