The easy way to fix that issue would be just to crop off
the bottom of the photo cause your taskbar is showing too.
Then resize the photo to fill the space needed .
If for personal use you can do that , if you wanted to upload
that animation because of copyright you would need permission to do so.
Any image that is Public domain or CCO give you permission to use so if
you want to load one of those animations just show a link to the public domain
or CCO permission .
The Official or Final version of DS11 still won't remove your items in question
you will still need to edit out un wanted items before creating your animation,
If not being used as an animation but just a still Image background you still need
to do the editing out as mentioned.
