PhotoBX+ is a simple Mac application that gives you access to over 2000 quality pictures taken in Northern Namibia. The program allows you to preview the offered photographs and acquire the ones you like at a reasonable price, directly from its interface.
The main screen of the utility displays thumbnails of the photos, but you can click over any of the pictures to preview them in a separate window. If you wish to acquire a portrait or landscape image, you simply click over the price listed under the desired photo and make the in-app purchase almost instantly.
The program also provides you with two additional options: to buy all photos (1 Touch Purchase) and to restore all purchases.
Other than that, not much more can be said about this application. It simply does what's being stated on its homepage: lets you buy pictures.
To conclude, I'd say it's worth acquiring the images provided by PhotoBX+. The program lets you buy high-quality photographs, is very simple to handle, and uses a small amount of CPU resources while running on your Mac.
