Following a discussion with the plant admins, I have made a change to how new incoming images are handled in the database.
If you are a member who has previously posted 10 or more images to the database (that's most of us!), your images will now bypass moderation and will be automatically approved and added to the plant you're posting to.
For new members who haven't posted 10 photos yet, those photos will go into the moderation queue for a moderator to approve. Once you get 10 approved photos, then you will no longer require moderation.
Finally, we have a system in place where we can add members to a "must need moderation" group. Moderators: if you have a member who you feel requires moderation, please tree-mail me their name and I will add them to that list. Members added to that group will have their images go into the moderation queue. I don't expect we'll have many members that need moderation.
