Responsive images unresponsive

[OilFreak]

I'm trying to implement responsive images into my website. They are not cooperating. No matter what I do, the 1440p image loads.

 <img  
      srcset="https://oilfreak.neocities.org/father_tuseday/father_tusedayhorrible.png 144w,
              https://oilfreak.neocities.org/father_tuseday/father_tuseday720.png 480w,
              https://oilfreak.neocities.org/father_tuseday/father_tuseday1080.png 720w,
              https://oilfreak.neocities.org/father_tuseday/father_tuseday1440.png 1080w,
              https://oilfreak.neocities.org/father_tuseday/father_tuseday4k.png 1440w"
      sizes="(max-width:480px) 144px,
             (max-width:720px) 480px,
             (max-width:1080px) 720px,
             (max-width:1440px) 1080px,
             (min-width:1441px) 1440px"
      src="https://oilfreak.neocities.org/father_tuseday/father_tusedayhorrible.png"
      />

You'll notice that the file names don't match up with their resolutions. The file names indicate the max resolution a monitor would be before switching to the next bigger image

Peas and thank you
