The below generally applies only when you upload a photo that does not belong to you.
Until today, our plant database did not support various licenses. Every photo uploaded to the system was a "Copyrighted, All rights retained" type license.
But we have had a few people who needed to upload a Creative Commons, GNU FDL, or Public Domain images to the database. In order to do that, the system needed to be programmed to support those licenses.
That work has been finished and the database now supports licenses.
So, when you upload a photo to the database, it now asks you what license you want to use. You can keep it the default (which is "All Rights Retained", the same as it has always been).
You can also choose the FDL, CC or PD. If you choose CC, you will get additional choices where you choose what kinds of restrictions are placed on this image.
If you don't understand all of this and you only upload your own photos to the database, just stick with the default option and nothing will change for you.
If you propose the import of a photo from the forums, it is given the most restrictive "All Rights Retained" license, as always.
The subject of content licensing is very complicated, so if anyone has any questions on this, feel free to post them below.
