Book cover front and back help

Greetings. I need a little help with my book please. I wrote a book using LibreOffice (wonderful program), most of it seems to be pretty self explanatory. However, I am having trouble with the first and last page, or book covers. They are jpg, and just want to place my cover first and back cover last separately than the content. It seems like I got the first working properly, but the last page is still registering it is the last page, instead of just showing the jpg. Does anyone know what I’m saying? It’s designed to be an ebook and a printable book. Plus, the jpg covers still have unnecessary headers and footers. Any help would be greatly appreciated, thank you LibreOffice community.

Are you aware of page-styles?
.
Your first/last pages will need their own page-styles, obviously without header/footer…

Also you can read the Guide:

there chapter 5 and 6. Good luck.
