# Slink: Image Sharing Platform
[](LICENSE)
**Slink** is a self-hosted image sharing platform built with [Symfony](https://symfony.com/) and [SvelteKit](https://kit.svelte.dev/)️.
Solves the problem of sharing images with friends, family, and colleagues without relying on third-party services. It also offers a platform for artists to share their work with the community. Additionally, developers may find it useful for self-hosting screenshots of personal projects, which can then be used on GitHub, portfolios, blogs, etc.
## Features
- **Authentication**: Users can sign up and log in to the platform.
- **User Approval**: Require user approval before they can upload images.
- **Image Upload**: _SVG_, _PNG_, _JPG_, _WEBP_, _BMP_, _ICO_ or _GIF_ images can be uploaded.
- **Share Links**: Users can share links to their uploaded images and customize the image size.
- **Upload History**: Provides an overview of all images uploaded by the user.
- **Storage Providers**: Support for _local_ and _SMB_ storage providers.
- **Explore Images**: Features a listing page of public images uploaded by other users.
- **Dark Mode**: Includes support for both _Dark_ and _Light_ modes in the application.
### Upcoming Features
> [!IMPORTANT]
>
> Those might be changed or removed in the future according to the community feedback and priorities.
- **CDN Support**: Support for _CDN_ _providers_ to reduce the load on the self-hosted server.
- **Storage Providers**: Additional storage providers like _AWS S3_, _Google Cloud Storage_, etc.
- **Database Support**: Support for additional databases like _MySQL_, _PostgreSQL_, etc.
- **Admin Panel**: An admin panel to manage users, storage, and other settings.
- **Dashboard**: Enhanced statistics and analytics for admin users.
- **Anonymous Upload**: Allow users to upload images without signing up.
- **Password Recovery**: Password recovery for users who forgot their password.
- **Email Notifications**: Email notifications for user approval, password reset, etc.
- **Public API**: A public API to access the platform programmatically.
- **Security Improvements**: Additional security features like rate limiting, brute force protection, etc.
#### Non-Functional planned improvements
- **Testing**: Comprehensive test coverage for the application.
- **Responsive Design**: A responsive design to support mobile and tablet devices.
- **Theming**: Add more themes and improve the default Light and Dark themes.
## Installation
To install the application, you need to have [Docker](https://docs.docker.com/get-docker/) installed on your system.
> [!IMPORTANT]
>
> **DO NOT** forget to set the `ORIGIN` environment variable representing your hostname. Otherwise, the application might not work as expected.
> Make sure to replace `https://your-domain.com` with your actual domain.
Just run the following command to start the application:
```bash
docker run -d \
--name slink \
-p 3000:3000 \
-v ./slink/var/data:/app/var/data \
-v ./slink/images:/app/slink/images \
-e ORIGIN=https://your-domain.com \
anirdev/slink:latest
```
### Docker Compose
You can also use [Docker Compose](https://docs.docker.com/compose/) to start the application.
```yaml
slink:
image: anirdev/slink:latest
container_name: slink
environment:
# Your application hostname
- ORIGIN=https://your-domain.com
# Require user approval before they can upload images
- USER_APPROVAL_REQUIRED=true
# User password requirements
- USER_PASSWORD_MIN_LENGTH=8
- USER_PASSWORD_REQUIREMENTS=15 # bitmask of requirements
# Maximum image size allowed to be uploaded (no more than 50M)
- IMAGE_MAX_SIZE=15M
# Storage provider to use.
# Available options are local and smb
- STORAGE_PROVIDER=local
volumes:
# Persist the database
- ./slink/var/data:/app/var/data
# Persist the uploaded images
- ./slink/images:/app/slink/images
ports:
# Expose the application on port 3000
- "3000:3000"
```
> [!TIP]
>
> If you are using Traefik, you don't need to expose the application on port **3000**. You can use Traefik to route the traffic to the application by adding the corresponding labels to the service.
## Configuration
The application can be configured using environment variables.
Simply set the environment variables when starting the Docker container or in your `docker-compose.yml` when using Docker Compose.
The following environment variables are available:
| Variable | Description | Default Value |
| -------- |--------------------------------------------------------------------------------------------------------------------------------------------|---------------|
| `USER_APPROVAL_REQUIRED` | Whether to require user approval before they can upload images. Available options are `true` and `false` | `true` |
| `USER_ALLOW_UNAUTHENTICATED_ACCESS` | Whether to allow unauthenticated users to access public routes. Available options are `true` and `false` | `true` |
| `USER_PASSWORD_MIN_LENGTH` | Minimum password length required for users. | `6` |
| `USER_PASSWORD_REQUIREMENTS` | Bitmask of password requirements. Sum of the following options: `1` (numbers), `2` (lowercase), `4` (uppercase), `8` (special characters). | `15` |
| `IMAGE_MAX_SIZE` | Maximum image size allowed to be uploaded (no more than 50M). | `15M` |
| `IMAGE_STRIP_EXIF_METADATA` | Whether to strip EXIF metadata from the uploaded images. Available options are `true` and `false` | `true` |
| `STORAGE_PROVIDER` | Storage provider to use. Available options are `local` and `smb` | `local` |
| `SMB_HOST` | SMB host to connect to. Required if `STORAGE_PROVIDER` is set to `smb` | `null` |
| `SMB_USERNAME` | SMB username to use. Required if `STORAGE_PROVIDER` is set to `smb` | `null` |
| `SMB_PASSWORD` | SMB password to use. Required if `STORAGE_PROVIDER` is set to `smb` | `null` |
| `SMB_SHARE` | SMB share to use. Required if `STORAGE_PROVIDER` is set to `smb` | `null` |
## Public Image Listing
The application has an optional image listing page where users can explore images uploaded by other users.
> [!NOTE]
>
> Only images marked as public will be visible here.
## Storage Providers
The application supports two storage providers: **local** and **SMB**.
Local storage provider stores the images on the local filesystem, while the SMB storage provider stores the images on a remote SMB server.
By default, the application uses the local storage provider.
> [!IMPORTANT]
>
> To persist locally saved images, you need to mount the `/app/slink/images` directory to the host filesystem.
> [!WARNING]
>
> If you are using SMB storage provider, you need to set `SMB_HOST`, `SMB_USERNAME`, `SMB_PASSWORD`, and `SMB_SHARE` environment variables.
## User Approval
By default, the application requires user approval before they can upload images. You can disable this feature by setting the `USER_APPROVAL_REQUIRED` environment variable to `false`.
If the user approval is enabled, you will have to activate the users manually with CLI command:
```bash
docker exec -it slink slink user:activate --email=
```
or
```bash
docker exec -it slink slink user:activate --uuid=
```
Newly registered users will be seeing the following message:
After the user is approved, they will be able to log in and upload images.
> [!NOTE]
>
> In the future versions, an admin panel will be added to manage users and their statuses.
## Security
Slink supports user authentication and user approval to prevent unauthorized access to the application. However, it's recommended to use a reverse proxy like [Nginx](https://www.nginx.com/) or [Traefik](https://traefik.io/traefik/)
to add additional security features like SSL, rate limiting, etc.
> [!WARNING]
>
> Be aware that as of now, the application does not have any built-in rate limiting or brute force protection.
> [!TIP]
>
> If you don't want to expose the entire application to the public, you can only expose the `/image` route via the reverse proxy.
## Overriding PHP Configuration
If you need to override the PHP configuration, you can do so by mounting a custom `php.ini` file to the `/usr/local/etc/php/conf.d/` directory in the container.
Here is an example of how you can override the `upload_max_filesize` and `post_max_size` settings:
```yaml
slink:
# Your existing configuration
volumes:
# Your existing volumes
# Overriding this file will allow to overcome the default 50M upload limit
# Change the values according to your needs for both upload_max_filesize and post_max_size
- ./custom-php.ini:/usr/local/etc/php/conf.d/uploads.ini
```
