Questions about these technology backgrounds
Can I use these images for free?
Yes, for personal and commercial projects. All we ask is a link back to BigFoto.com; the box at the top of the page has a credit link you can copy.
Are these real photos?
No. These backgrounds were made with AI (Stable Diffusion XL 1.0) for BigFoto, then picked and checked by hand. Every file is marked as AI-generated in its metadata (IPTC digital source type), and the photo viewer labels them too. Our real photos are in the other collections.
Can I use them in a business presentation?
Yes. They are free for commercial use, including slides, websites and reports; a link to BigFoto.com is all we ask.
