Using large, high-resolution images in this PowerPoint game can cause lag and slow performance. To prevent this, I’ve included a simple image-resizing utility called ImageResizerSetup-3.1.2.exe that quickly creates smaller versions of your photos.

After installing the utility, select all your photos in File Explorer, right-click, and choose Resize Pictures. Select Large, and the tool will create reduced-size copies of your images in the same folder.

Once the resized images are created, be sure to delete or move the original high-resolution files out of the pictures folder so the game doesn’t load them.
