Pulse

Pulse is a reliable application that can decorate your desktop with a sequence of wallpapers, from local folders or online sources. The application runs in the background and automatically downloads images from the indicated sources, then sets them as desktop wallpapers.

Pulse allows you to easily configure the photo sources, by selecting the providing websites from the Options window. The currently supported sites include Google Images, National Geographic, Wallbase, custom MediaRSS Feed or NASA Astronomy Picture of the Day collection.

The program can download a large series of images from either of the specified websites and set each new one as wallpaper. The downloaded content can be filtered by certain parameters: picture size, color and query. Select either of the sources and click the Settings button to manually configure these parameters.

The downloaded files are saved on your computer for a specified period and they are automatically deleted when the time is up. You may also clear the cache at any time or change the default download folder.

Pulse can also alternate the pictures already stored on your computer, as desktop wallpaper, as long as you indicate the local path and supported formats.

The program can be set to automatically change the picture on startup and you may enable the automatic sequence based on a timer.

The time interval ranges from seconds, minutes to hours and days. You may enter any (supported) value for each time unit. You can manually create new settings, by setting the label and description: for example sync aero glass color.

Pulse can be manually operated from the system tray menu: change the picture, pause the timer or block image. You can set the application to run with Windows, automatically stop its activity when another program/file is in full-screen mode, plus enable the image pre-fetching. This option allows it to download images in advance.
