Welcome to the forum.
I will help you out on a picture. The hard part is done. Helps to tell us what state you live in,or what country for an ID on your tree.
This is how I got your picture into this post.
I like to go to whatever post or start a new topic first to include a picture.Go to your gallery,it will open in a new window.Click onto your album,then click onto whatever picture you want,it will get bigger,than scroll down a little to find,Insert Image In Post,click onto that,click Yes and that is it. Some have to copy/paste the link to work.I like to hit the enter key at least once or twice to move the picture down away from what I am typing. The enter key really helps to leave some white space if posting more than one picture or posting a comment. Use the preview button to see how it looks and modify it if needed.
