Joseph, I proposed to move both of your above photo's for Sinningia Gabriel's Horn to the database but you can add any of your photo's to the database, whether old or new pictures.
At the top of the page on the left hand side just click where it says ATP Plant Database and then type in the name of the plant you are looking for. When you get to that plant entry under "Adding Actions" click on "Upload a photo" after it uploads it automatically goes into a queue for the database administrators and once approved you will get system messages letting you know the photo was added.
If you have any difficulties just holler and one of us will help.
