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.

Features
