Our site is going through some changes and at the moment the images are not available from PlantVillage.org. But the images are still open access and available to the community. The licence is Creative Commons 3.0 Share and Share Alike.
We are still figuring out a way to make them easy for people to access. In the meantime people can just let David Hughes know (firstname.lastname@example.org
) what images you want and we will put them in a dropbox folder for you.
