PEOPLE ICONS
Placeholder avatars are the most-used part of this set, and they solve a real problem: an interface mockup needs a face in it before any real user exists. Alongside them sit thought and idea marks, beauty and fashion symbols, faces, arms, brains, sleep imagery and profession icons such as engineers. A few named public figures appear, including Mark Zuckerberg, and images of living people are best kept to editorial and reference use rather than advertising. Files are transparent PNGs that stay clean at the small circular sizes avatars usually take, layering over a coloured tile or a photograph with no block behind them. Product teams use them in profile and account interfaces, HR software for directories, and presenters for audience and persona slides. Free to grab and reuse.
