Flasher is a hidden prank program that allows you to flash any image to the computer screen, almost like a subliminal message! Flasher supports JPG, BMP, EMF, WMF and ICO formats. All you have to do is specify the image you want to flash and the amount of time between flashes. When the software is not flashing the image to the screen, it hides itself within Windows until the next time it needs to flash.

This is a great prank to play on your friends. Imagine flashing the logo of the opposing sports team or a photo of their ex. The possibilities are endless so download Flasher today -- it's free.

Command line Options

There is NO user interface to this application. By default, if you do not specify a command line, the RJL Software logo will flash. You can specify your own image and time to flash by using the following command line.

flasher.exe [seconds to delay] [path to image file]

For example:


This would flash the "ugly.jpg" file to the screen every 60 seconds.

How to close

Move your mouse pointer to the TOP LEFT corner of your screen. This will stop the program from running in memory. If you have successfully moved your mouse in the correct position, the program will close and display an About Box Screen. Once you close this screen, the program will exit. Exiting the software will allow Windows to delete the file.
