Evan asked me if it is possible to add the date to some photos

The thread "Nice documentation" in Photo of Zizotes milkweed (Asclepias oenotheroides)

I'm agree. The date and location for wild plants are important. But I don't know where and how to be add.

I think it is useful and a mention for plant if it is growing wild or a cultivated plant.

Hi, Justin. For most of us, the dates are recorded by our cameras and are automatically added to the photo information. If your camera is not set to record the date, you can add that information on the photo caption line when you submit a photo. In the case of an already submitted photo, you can click on the photo to enlarge it, scroll down to the "Actions" offered, choose "Edit this image's caption, details, etc.," and enter the date and any other information you wish to provide on the caption line.

Thank you Zuzu.
My camera record the date. Probably it is not added because I imported the pictures from forum and not submit them directly to database.
Soon I will start to fill the date and location.
