I run several online shops that sell images of insects, nature or brains as digital downloads or as physical products – have a look:
My Etsy store – downloads and physical items, including Ukraine fundraiser products
My Alamy store – digital images in insects and nature
My Zazzle store – a wide range of physical products (from postcard to magnets to bags and beyond), embellished with my photos. Designs are customisable!
My eBay store – physical items, including Ukraine fundraiser products
