Hi Cheryl,
from me too!
Yep, you will find a lot of us here at garden.org are former members at DG, if that's the "other" place you are referring to.
I see you have one photo in the database (Daylily) so I see you must have figured it out but if you ever have trouble finding a database listing for a plant, just give a shout out and someone will help!
It's easy to upload photos once you get used to it. When you find the correct database entry; for example:
Sedum (Hylotelephium spectabile 'Herbstfreude') Look over to the left and under where it says Actions, the first item is Upload a Photo. Click there and follow the steps and don't forget to scroll down and click submit. Photos go into a queue for database administrators to approve and you will get a system message once it's done.
Again, if you have any trouble at all, don't hesitate to ask. It sometimes takes a little while to get used to a new site and the way things operate but garden.org is truly user/member friendly! LOL, I've been a member here since the beginning and I still get confused and have to ask for help sometimes!
