Eddie answered the how and I shall address the should.
If you are inferring using copies of images from other websites such as Find A Grave, WikiTree frowns upon this for copyright reasons. If there is a Find A Grave memorial for the Profile you would like the image to be seen, just add a link in the text section of the biography as an information pointer to that memorial using the Find A Grave template. This will take them right to the memorial page on Find A Grave.
You can add text in front or after the template to be more specific.
If not from Find A Grave, you can still add the link to that site by this method. The square brackets hide the url from view when viewing in normal fashion. As above, you can add text to help the reader, but here you put a space after the url and type in your info there.
[https//some.grave.com/somebody Somebody's Grave Memorial] This will show up Sombody's Grave Memorial to let them know its a url. If you don't add the text, it will just appear as afootnote number such as (5).
If you are taking the photos, then follow Eddie's directions and please be sure to add the cemetery to the photo comment.
You may also want to look into adding the cemetery category to the Profile itself . You can view all of the United States cemeteries already registered in WIkiTree here: Also many other counties have cemeteries listed as well. Category:United States Cemeteries
I add a cemetery category to all of my Profiles where one is available or create a new one where it is not. Amazing sometimes when you look at the cemetery listing of someone you just added and there is a relative there from another branch of the family.
