Welcome to the Forums!
To answer your question about photo posting, please take a look at our community rules
and forum FAQs
(you can find links to them on the blue band at the bottom of every forum page, and there's also a link in this thread
in the Announcement section), because we have some fairly strict rules about what sort of photos can be posted here. Copyrighted photos can't be posted here unless you've obtained written permission from the copyright holder; I've deleted the photos you posted here because they're copyrighted, but at least you figured out how to do it!
If you want to add copyrighted photos to your posts, you can just post a link to the photos on the original photo agency or royal family website; alternatively, if you have photos stored at a photo-hosting site, you can post links to them there (although you may be running into copyright problems with the photo-hosting site by doing that). If you've taken photos yourself or are wanting to post photos that are in the public domain, feel free to post them on the forum directly. And always feel free to contact any of the moderators or admins for help with this if you don't understand it.
