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.
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).
Also don't forget to change bot's working mode. Dict key `"mode"` contains keys `"post"` and `"submit"`, each of those can be either `true` or `false`.
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`.
All localization files are located in the `locale` folder, otherwise in folder specified in config file. Just copy locale file of your choice, name it in accordance to [IETF language tags](https://en.wikipedia.org/wiki/IETF_language_tag) (if you want your locale to be compatible with Telegram's locales) or define your own name. Save it as json and you're good to go. If you want to change default locale for messages, that cannot determine admin's locale - edit `"locale"` parameter in the `config.json`. If this locale is not available - `"locale_fallback"` will be used instead. If both are not available - error will be shown. For console output and logging locale you should edit `"locale_log"`.
