Here's how to add tags. The example I'm giving is using the Graph API Explorer: https://developers.facebook.com/tools/explorer

See also the tags section of: https://developers.facebook.com/docs/reference/api/photo/

1. request a token with the appropriate permissions (see above link for the permission you will need)
2. Enter in your photo ID and click Get
3. Add /tags to the graph url and click Get to see what tags already exist
4. Change Get To Post in the dropdown
5. Click Add a field, Name= to, Value= a friends id or your id
6. Click Add a field, Name = x, value = 45
7. Click Add a field, Name = y, value = 45
8. Click Submit
9. Change Post back to Get in the dropdown
10. Click Submit to see the new tag
11. Of course the person you're tagging in the photo might need to approve the tag if they have their security features set as such.
