Shim is a free software image hosting platform, designed to be simple and functional.
Shim is under development, you can copy the example configuration file and provide the location as a required argument.
It's a simple application and the code is quite small, understanding it should not be an issue.
Shim is a learning project for me, so while contributions are appreciated and accepted, I prefer anything to be emailed to the mailing list.
Shim is a abbreviation of the words SHare IMages.
