Random Photo Screensaver 

Random Photo Screensaver allows you to create screensavers with your own photos. The application lets you create great slideshows with your images, which can be in separate folders. It offers multiple customization options, so you can create a slideshow completely to your liking. You will be able to select the background color, lapse between each photo and size of the photos. You also can apply animated transitions, set the program to rotate the images automatically, and display filenames. Moreover, a digital clock and a calendar can be shown there.

In addition to this, you can select a set of images to be displayed as a wallpaper. You can choose when you wish to change the wallpaper, customize filename fonts, and select the background color. The program can convert RAW files to JPG on the run, but the screensaver may run a bit slow while the images are being converted. A great thing is that while the slideshow is running, you can use predefined keyboard keys to customize the screensaver.

In short, if you are looking for an application that allows you to create your own slideshows with your photos or images that can be used as wallpaper or screensaver, Random Photo Screensaver may be a good choice.
