Oops, I forgot ... When you find a plant in the database and click the green area that says Add An Image, that is prompting you to add a photo to that database entry.
Maybe this will make more sense. For adding an image to your post:
1. Go to the database and find the photo you want
2. Click on the photo to enlarge it
3. Go to the top of the page and highlight the url which will automatically copy it
4. Go back to the thread and type your message
5. Click "Paste" to have the link show up in your message
6. Click "Preview" if you want to proof read and view your message with the photo
7. Click on 'Finished"
