Slink is a self-hosted image hosting and sharing platform that allows users to upload, organise and distribute images from their own server. It provides an alternative to third-party image hosting services, giving individuals and organisations control over their image libraries, storage infrastructure and access permissions.
The software combines private image hosting with public gallery functionality. Users can maintain personal image collections, share selected content with others and manage their uploads through a web interface. It accommodates photographs, illustrations and screenshots, making it useful for personal collections, collaborative projects and publishing images on websites or in documentation.
Slink also provides multi-user capabilities, allowing administrators to manage accounts and oversee content published on their instance. Its authentication, storage and integration options make it suitable for both personal installations and shared image hosting services.
This is free and open source software.
