I disagree. I've been a UI / UX designer for various pieces of software and the thing I miss in all the collected screenshots online _is_ text. It makes things more easily searchable and comparable. For example, is a health bar vertically or horizontally positioned? Top right or top left? What's the used color?

All these things could show me the obvious choice when designing a health bar in a specific type of game or interface.

No website with screenshot (or otherwise UI based visuals) in collections has this searchable content.

So for me, as a UI designer, I would definitely benefit from more textual information.
