I checked MDN docs about HTMLImageElement.

But i couldn't find any information about mimeType.

I was able to find few docs about how to get mineType from File Object

But i need to get mimeType from url string

In my javascript logic i actually load the source to create Image object.
I hope i can find mimeType from this.

       const image = new Image();
       image.addEventListener("load", () => callBack(image));
       image.src = url;
