Tested using [Google PageSpeed Insights](https://pagespeed.web.dev/).

| | [rimgo](https://pagespeed.web.dev/report?url=https%3A%2F%2Fi.bcow.xyz%2Fgallery%2FgYiQLWy) | [Imgur](https://pagespeed.web.dev/report?url=https%3A%2F%2Fimgur.com%2Fgallery%2FgYiQLWy) |
| ------------------- | ------- | --------- |
| Performance         | 91      | 28        |
| Request count       | 29      | 340       |
| Resource Size       | 218 KiB | 2,542 KiB |
| Time to Interactive | 1.6s    | 23.8s     |

### Privacy
Imgur collects information about your device and uses tracking cookies for advertising, this is mentioned in their [privacy policy](https://imgur.com/privacy/). [Blacklight](https://themarkup.org/blacklight) found 31 trackers and 87 third-party cookies.

See what cookies and trackers Imgur uses and where your data gets sent: https://themarkup.org/blacklight?url=imgur.com

## Usage
Replace imgur.com or i.imgur.com with the instance domain. For i.stack.imgur.com, replace i.stack.imgur.com with the instance domain and add stack/ before the media ID. You can use a browser extension to do this [automatically](#automatically-redirect-links).

Imgur: `https://imgur.com/gallery/j2sOQkJ` -> `https://rimgo.bcow.xyz/gallery/j2sOQkJ`
Stack Overflow: `https://i.stack.imgur.com/KnO3v.jpg?s=64&g=1` -> `https://rimgo.bcow.xyz/stack/KnO3v.jpg?s=64&g=1`

## Instances
Open an issue to have your instance listed here! Instance privacy information is required for the instance list, see [Environment variables](#environment-variables).

> NOTE: The `instances.json` in this repo file is deprecated and will not be updated. Use the new InstancePage API https://rimgo.codeberg.page/api/instances.json (may change, documentation coming soon)

## Automatically redirect links

### LibRedirect
Use [LibRedirect](https://github.com/libredirect/libredirect) to automatically redirect Imgur links to rimgo!
- [Firefox](https://addons.mozilla.org/firefox/addon/libredirect/)
- [Chromium-based browsers (Brave, Google Chrome)](https://github.com/libredirect/libredirect#install-in-chromium-brave-and-chrome)

### GreaseMonkey script
There is a script to redirect Imgur links to rimgo.
[https://codeberg.org/zortazert/GreaseMonkey-Redirect/src/branch/main/imgur-to-rimgo.user.js](https://codeberg.org/zortazert/GreaseMonkey-Redirect/src/branch/main/imgur-to-rimgo.user.js)

### Redirector
You can use the [Redirector](https://github.com/einaregilsson/Redirector) extension to redirect Imgur links to rimgo with the configuration below:

* Description: Imgur -> rimgo
* Example URL: https://imgur.com/a/H8M4rcp
* Include pattern: `^https?://i?.?imgur.com(/.*)?$`
* Redirect to: `https://rimgo.example.com$1`
* Pattern type: Regular Expression
* Advanced options:
  * Apply to:
    * [x] Main window (address bar)
    * [x] Images

For Stack Overflow images:
* Description: Stack Overflow Imgur -> rimgo
* Example URL: https://i.stack.imgur.com/BTKqD.png?s=128&g=1
* Include pattern: `^https?://i\.stack\.imgur\.com(/.*)?$`
* Redirect to: `https://rimgo.example.com/stack$1`
* Pattern type: Regular Expression
* Advanced options:
  * Apply to:

## Install
rimgo can run on any platform Go compiles on.

> It is strongly recommended to use [Caddy](https://caddyserver.com/) as your reverse proxy. Caddy is simple to configure, automatically manages your TLS certificates, and provides better performance with support for HTTP/2 and /3 (allow UDP port 443 in your firewall to use HTTP/3).

### Docker (recommended)
Install [Docker](https://docs.docker.com/engine/install/) and [docker-compose](https://docs.docker.com/compose/install/), then clone this repository.
```
git clone https://codeberg.org/video-prize-ranch/rimgo
cd rimgo
```

Edit the `docker-compose.yml` file using your favorite text editor.
```
nvim docker-compose.yml
```

You can now run rimgo.
```
sudo docker-compose up -d
```

#### Automatic updates
[Watchtower](https://containrrr.dev/watchtower/) can automatically update your Docker containers.

Create a new `docker-compose.yml` file or add the watchtower section to your existing `docker-compose.yml` file.
```yml
version: "3"
services:
  watchtower:
    image: containrrr/watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
```

### Build from source

#### Requirements
* Go v1.16 or later

Clone the repository and `cd` into it.
```
git clone https://codeberg.org/video-prize-ranch/rimgo
cd rimgo
```

Build rimgo.
```
go build
```

You can now run rimgo.
```
./rimgo
```

To include version information use:
```
go build -ldflags "-X codeberg.org/video-prize-ranch/rimgo/pages.VersionInfo=$(date '+%Y-%m-%d')-$(git rev-list --abbrev-commit -1 HEAD)"
```

(optional) You can use a .env file to set environment variables for configuration.
```
cp .env.example .env
nvim .env
```

## Configuration

rimgo can be configured using environment variables. The path to the .env file can be changed the -c flag.
