Sparrow Photography displays a responsive grid of nature photographs, with each image linking to a detail page showing the photo's name, description, and price. The gallery uses the native Fetch API to retrieve photo data from an external JSON endpoint, while sessionStorage caches the response to avoid repeated network requests. JavaScript's URLSearchParams extracts the photo ID from the query string to render the correct item, and CSS Grid with media queries arranges the images across two to four columns depending on viewport width. The interface is built with plain JavaScript modules and semantic HTML, with no external visualization libraries.
