As many people requested, now Fotowall has become really Open Source (GPLv2) and is publicly hosted on the net!!
Its new home is http://www.enricoros.com/opensource/fotowall, and for celebration 0.21 was released, with a new Icon, WinXP+ binary file and the full-res version of tutorial video I put on YouTube.
Suggestions are more than appreciated,
Thank you all for your support and drive
