Lovely photos! You should upload your pictures directly to the database instead of sharing them as a comment to a photo. Here's the link to this Agave in the database: Maguey Mezortillo (Agave univittata)
Look over on the left side of the page and select Upload a photo and follow the steps. Your pictures will go into a queue to be approved by the database administration and once approved, you will get a system message telling you they've been added!
