I can't find any link in the drop down menus to upload photos from. Where is it hiding? I've done it before, so something on the site must have changed. This shouldn't be so difficult.

Look on the bottom right above the smilies and there is a tab button called Upload an Image, click it. Then choose the photo by the file name you want to install and click it. You have uploaded a photo.

Rhododendron (azalea) Mandarin LIghts

That's works on this thread, but where do I do it from in general, to post to the system? Plants database doesn't have a reply box, and only asks for new plants, not additional photos of those already listed.

Go to this page to find the plant in the database (dropdown under "Plants Database"):

https://garden.org/plants/sear...

and that will send you to this page about the plant in question:

Azalea (Rhododendron 'Mandarin Lights')

Where you will find the option to "Upload a photo".

Thanks, I wasn't clicking on the plant and was only getting options to return to the database homepage or add a new plant. How do I just add a landscape photo in general?

The landscape photos section is now called Plant Combinations (for pictures of more than one different plant):

Thanks much. Got it now. Recently replaced my old camera, so I'll have to get into the habit of posting now, before I forget how to again. 3 years of assorted iris plantings are just about to have their first full bloom here. Just might give me some practice.
