Find duplicate photos with the free Phomanto alpha version

You want to find duplicate photos on your hard disc, free up space and avoid confusion? You can try Phomanto, a little tool I've developed that finds and removes duplicate photos. It is still in alpha state (that means probably a lot of bugs, missing features, etc.), but you should be able to use it for its main purpose: removing duplicate files. I am looking forward for your feedback and comments concerning the program. If you like it I will consider extending it to a more complete photo management software, so tell me what you think.
