To start your gallery, just click on Gallery in the left column, you'll see MY PHOTOS in the first full pink line...click on that. In that same pink line at the right side, you'll see UPLOAD PHOTOS...click there. Browse, choose and upload. There will be options along the way for titles and descriptions.
PLEASE be sure to choose the Member's Galleries icons if the picture you are posting is not part of an Orchidboard Project...any gallery named for a Project is to be used ONLY for OB Project plants... thanks
