As far as adding your own pics to your personal plant list...I'm unsure. On the pages up above there is the option of 'add this plant to your list' but I don't think it will link up directly to your picture but rather the page where your picture is. (does that even make sense?). Once you add it to your list though you can edit in a small comment to indicate it is a NOID plant with perhaps a direct link to your pictures of them.
