HTMLImageElement: Image() constructor
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Image()
constructor creates a new HTMLImageElement
instance. It is functionally
equivalent to 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-
The width of the image (i.e., the value for the
width
attribute). height
Optional-
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
HTMLImageElement.width
and HTMLImageElement.height
of the
resulting instance. The intrinsic width and height of the image in CSS pixels are
reflected through the properties HTMLImageElement.naturalWidth
and
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
<body>
:
<img width="100" height="200" src="picture.jpg" />
