Need help selecting several sheets and copying as image to word

Hello Excel Forum!
So i am very new to coding and need to use a macro which allows me to copy a range of excel cells as a picture to a word document.
I have found some code which allows me to do that for the active sheet, but i need it to apply for all the sheets in the excel document which i define.
All help is appreciated!

Furthermore, if possible, i would like to set the word document to "Size: A3" "Orientation: Landscape" and "Margins: Narrow".
