Chat backdrop

Everyone in the chat sees the backdrop, viewing is free. Setting it needs STAR. In the public chat the presets are free.

Chat	Who sets it	STAR
Direct	either person	required
Group	owner and admins	required
Saved	you	required
Public chat	owner and moderators	presets free, own photo needs STAR

Right click the chat -> Backdrop

Or Info -> Backdrop. No such item: you lack the rights, a lock is shown. STAR needed: you see an offer.

Pick a backdrop

A preset (Aurora, Vinyl, Sunset and more), Own photo or From storage. No backdrop removes it.

Done

Press Done.

Own photo and From storage work as in a room: Own photo as backdrop. The list of presets: Room chat.

I do not want to see it

What	Where
Hide backdrop	Right click the chat. Only for you. Show backdrop brings it back
Report backdrop	Same place. If it breaks the rules
Clear backdrop	Same place, for those who can change it

You can change it 6 times in 10 minutes per chat. After that: Too often.
In a direct chat, group or Saved, if the STAR of the person who set it ends, the backdrop goes back to the default look. In the public chat a preset stays.
Room backdrops are separate: Room chat.
