# ChatAvatarSetter
|
|
|
|
A bot that updates a group or channel's avatar using a photo sent to the bot.
|
|
|
|
## Functionality
|
|
|
|
When the bot receives a photo message, it downloads the highest-resolution version of the photo
|
|
and sets it as the chat photo for the chat the message was sent from. If the operation fails (e.g.,
|
|
due to missing admin rights), the bot sends an error message back to the user.
|
|
|
|
