slink, a self hosted image sharing and upload server, ready to receive and share images privately from first boot.
Overview
Slink is an open source, self hosted image sharing and upload server. It gives you a private drop in replacement for public image hosts: users upload images through a clean browser interface, each image gets a shareable link, and you keep the files and the audit trail on infrastructure you control. It pairs a PHP API with a modern browser frontend and stores images and metadata locally by default, with optional object storage backends. Registration can require admin approval, guest uploads are off by default, and EXIF metadata is stripped on upload, so it suits teams and individuals who want the convenience of an image host without handing their images to a third party.
Why the cloudimg image
cloudimg ships the official upstream release unmodified, run the supported way and pinned by image digest, so what you run matches the project exactly. Nothing ships with a known secret: a unique application secret and signing keypair are generated on the first boot of every instance, and a per instance administrator account with a random password is seeded automatically and written to a root only file, so no instance is ever reachable with a default login. Secure defaults are applied out of the box, new sign ups need administrator approval and anonymous uploads are disabled. The image is built on a fully patched base with unattended security upgrades enabled, and every instance is paired with a step by step deploy guide verified against a real running instance. Backed by 24/7 cloudimg support.
Common uses
- Run a private, self hosted image host for a team so screenshots and image links never leave infrastructure you control
- Share images with shareable links while keeping registration behind administrator approval and guest uploads disabled
- Provide a lightweight upload endpoint for internal tools and documentation with EXIF metadata stripped on upload
