The marketing team may need images of the people who make up a company for various purposes, including websites, brochures, and presentation slides. Some companies may request that staff submit their images. This approach may lack consistency and sometimes even a massive difference in quality between the different pictures. Low-quality images can make your brand look cheap.
A possible solution would be to hire professional photographers locally and provide a style guide to follow. Digital backgrounds can be created and used to ensure consistency across images coming from different photographers.
