Yes you find the plant in the database, scroll down past all the photos to a section that say adding actions and under that will be a link that says upload photo. Click on that and there will be a green button that says Upload an image. Clicking on that will open a window on your computer where you can search for the photo you want to upload. Find the photo and upload it. Once it is uploaded it will show up on you plant list. One note after you upload a photo it takes a little time to show up in the database. If you have never uploaded before, it has to be approved by a database moderator. Once you have uploaded a certain number of photos (I'm not sure what the threshold is) they will no longer need to wait for approval.
