ZapDropbox

ZapDropbox is a software application developed specifically for helping you change the wallpaper on multiple computers at the same time using a set of straightforward actions. In order to accomplish such a task, the program allows you to make use of your Dropbox or NetDrive image collection, and mount FTP sites as hard drives.

Look for the tool in the system tray

You can find ZapDropbox running in an unobtrusive mode in your system tray. A right-click on its icon allows you to perform several tweaks on the go, namely play sound notifications when the wallpaper is changed or another hour passed, set the next or previous wallpaper, and switch between different modes (e.g. full screen, filename picture).

Configuration settings

A set of dedicated parameters are hidden under the hood for helping you configure the wallpaper changing process in detail. You are allowed to run ZapDropbox at Windows startup, change wallpapers in a random order, and automatically change all wallpapers at a certain number of minutes.
What’s more, you can alter the wallpaper upon running the program, enable or disable sound notifications, specify the saving directory where images are stored, include subdirectories, and show desktop notifications.
Other important tweaking options worth being mentioned enable you to set the image size, show the filename of the pictures and adjust the text in terms of size, color, and opacity, apply several image effects, as well as disable a portrait display mode for photos.
Tests have shown that ZapDropbox carries out a task quickly and without errors. It does not eat up a lot of CPU and memory resources so the overall performance of the computer is not hampered.

Final remarks

To sum things up, ZapDropbox comes packed with several handy features for helping you remotely set the wallpaper on multiple PCs at the same time. However, not all of the application’s configuration settings can be described as highly intuitive so you may need some extra time to decode them.
