HTMLImageElement: Image() constructor

{{APIRef("HTML DOM")}}

The Image() constructor creates a new {{DOMxRef("HTMLImageElement")}} instance. It is functionally equivalent to {{DOMxRef("Document.createElement()", "document.createElement('img')")}}.

[!NOTE] This function should not be confused with the CSS image() function.

Syntax

new Image()
new Image(width)
new Image(width, height)

Parameters

• width {{optional_inline}}
  • : The width of the image (i.e., the value for the width attribute).
• height {{optional_inline}}
  • : The height of the image (i.e., the value for the height attribute).

Usage note

The entire bitmap is loaded regardless of the sizes specified in the constructor. The size specified in the constructor is reflected through the properties {{DOMxRef("HTMLImageElement.width")}} and {{DOMxRef("HTMLImageElement.height")}} of the resulting instance. The intrinsic width and height of the image in CSS pixels are reflected through the properties {{DOMxRef("HTMLImageElement.naturalWidth")}} and {{DOMxRef("HTMLImageElement.naturalHeight")}}. If no size is specified in the constructor both pairs of properties have the same values.

Examples

const myImage = new Image(100, 200);
myImage.src = "picture.jpg";
document.body.appendChild(myImage);

This would be the equivalent of defining the following HTML tag inside the {{HTMLElement("body")}}:
