I am a beginner at HTML and Stack Overflow. I was trying to make this thing where there is an image that changes every few seconds. I was able to get this done but for some reason although all my 3 pictures show up, I have an extra image error icon that shows up once in a while and I don't know why. I only have 3 images so I am not sure why this image error icon shows up. Any help would be greatly appreciated.

Click the Preview button on the top right corner and it should work.

Generating the random index is not correct. Use images length (3) instead of 4

let random = Math.floor(Math.random() * images.length);
