The official Star Wars web site has some pictures that you can use as virtual backgrounds for your Zoom or Teams online calls. Also great for PowerPoint slides.
Go to https://www.starwars.com/news/star-wars-backgrounds , click on an image to open the full version then right-click on the picture and choose ‘Save image as …’ or equivalent on your browser.
PowerPoint too
Though the site doesn’t mention it, the same images can be added to PowerPoint slides. The Star Wars images are nicely proportioned to fit into both PowerPoint slides (Normal 4:3 and Widescreen 16:9).
