No, by default, Wall Photo Maker is not working on Mac OSX because it has been developed to support only the Windows operating system. But given the fact that it's a very simple application, there might be ways you can use to run it on OSX.
The easiest and safest way is to simply install Wine Bottler. Wine Bottler installs as a Mac application and allows you to run Windows applications without the need to actually have the Windows OS running. It contains some general libraries and modules that make it possible to achieve this.
