What does "写真" mean in the comments?

I've been noticing people commenting "写真" on TikTok posts. Does anyone know what it means and why it is showing up in so many comment sections?

It means photograph. Not sure why people are posting it however. Maybe to indicate they took a screenshot or like the photo?

Stuff people learned on rednote during that tiktok ban. Lots of people learned how to read and write Chinese.

If you don't get the option to translate in the app, can't you translate the words using your phone?
