This bot is used for one and only task - post pictures from my personal archive. Here's its source code so you can also host a bot and have fun with it. Just don't exepect it to be brilliant. It is not. But hey, you can always fork it ;)
To make this bot run at first you need to have a Python interpreter and git. Google is your friend finding it. You can also ignore git and simply download source code, should also work fine. After that you're ready to go.
These are not required but can make the bot run a bit faster
4. Configure your bot with a favorite text editor:
`nano config.json`
You can edit with vim, nano, on Windows it's Notepad or Notepad++. Whatever.
If you don't know where to find bot_token and your id - here you can find some hints: [get bot token](https://www.siteguarding.com/en/how-to-get-telegram-bot-api-token), [get your id](https://www.alphr.com/telegram-find-user-id/), [get api_hash and api_id](https://core.telegram.org/api/obtaining_api_id).
To use your bot of course you need to have a channel or group otherwise makes no sense to have such a bot. [Here](https://stackoverflow.com/a/33497769) you can find a quick guide how to add your bot to a channel.
Of course bot cannot post something from nothing. Configure your `config.json` what media types bot should post (`"posting", "extensions"`), when to post them (`"posting", "time"`) and also where to find them (`"locations"`). You can also move them when sent by setting `"posting", "move_sent"` to `true`.
