Look for something that gets at least 5 hours of direct light a day, the more the better though. Also East/West spots like stream banks, swamps, fields. They will get the most sun of course as opposed to a North South field etc...
Look up Shamans Canadian Outdoor or Good soil and a Burlap Sac.

I am about to start journaling my outdoor grow in the swamps with the Burlap Sac method. I wouldnt see a problem with pics of an outdoor grow any more than with an indoor grow. If you are nervous just make sure you or anything you could use to reference you to the picture or give a idea as to location is not in the photo.
