You can't download the application since there is no website to acquire it from. I've checked various ones for a download link, but they all pointed to the same source that doesn't load. In this case, the software might be considered as being discontinued or in a maintenance mode.
The only thing you can do is to wait until the website comes back (if it will ever do that!) or switch to an alternative. You can pick some apps from this link: http://software.informer.com/search/image+editor
