Lutim – self-hosted image sharing

Lutim (Let’s Upload That Image) is a self-hosted image sharing application for uploading photographs, screenshots and other image files and making them accessible through links.

It focuses on straightforward image hosting rather than maintaining a permanent, organised photograph library. Uploaded images can be viewed or downloaded by recipients, with configurable retention periods controlling how long they remain available.

Lutim also supports optional server-side encryption. When encryption is enabled, the application does not retain the encryption key on the server, allowing the key to be supplied through the sharing link.

Its web interface can be used without JavaScript, while additional browser functionality provides convenient uploading and gallery management.

This is free and open source software.
