Welcome to **Slink**, a powerful self-hosted image sharing platform designed to give users complete control over their media sharing experience. Built with [Symfony](https://symfony.com/) and [SvelteKit](https://kit.svelte.dev/), Slink enables seamless and secure image sharing without relying on third-party services.

**[Live Demo](https://demo.slinkapp.io)** | **[Documentation](https://docs.slinkapp.io/)**

## Why Slink?

Slink solves the problem of sharing images with friends, family, and colleagues in a private, self-hosted environment. It's also ideal for:

- **Artists**: Showcase artwork in a community-focused platform.
- **Developers**: Host and share screenshots for GitHub, portfolios, blogs, and more.
- **Anyone**: Take control of image privacy and hosting.

- **Privacy-First Shares**: All shares are private by default; access is granted only to whoever holds the link.
- **Password-Protected Shares**: Optionally require a password to view a shared image.
- **Expiring Shares**: Set an expiration so a share auto-revokes after a chosen time.
