How can you make a picture pop up full screen at a certain time using notepad just like a screen saver?

To create a full-screen image pop-up using Notepad, you can write a simple batch script. Open Notepad and enter the following code:

<code class="language-batch">@echo off
timeout /t <seconds> > nul start /max mspaint <path_to_your_image>
</code>

Replace <seconds> with the desired wait time before the image appears, and <path_to_your_image> with the full path to your image file. Save the file with a .bat extension, and when you run it, the image will open in Paint in full screen after the specified time.
