So now, Gerrye, I'm guessing you want to add your photo to the "Spectacles" question in the 52 Ancestors series. That is at:
https://www.wikitree.com/g2g/998321/52-photos-week-11-spectacles?start=0#a_list_title
The first thing I suggest you do is log in before you post (you will have to in order to do some of what I'm suggesting).
Second, no one can see your photo because you posted it to your own profile, where it is protected. A quick way to fix that is to also add your photo to a public profile such as one of your grandmothers'. (Go to the photo, click on it, and then on the right-hand side, you will see "In this image" with an add/edit option. Add your grandmother's WikiTree ID.)
Then to upload to G2G, see this helpful explanation provided recently by Melanie Paul (you may need to scroll up to the top of the page):

Good luck!
