Image (v2)

Image component written in HTL that renders an adaptive image.


  • Smart loading of optimal rendition
  • In-place editing, cropping, rotating, resizing and image map definition
  • Responsive image map resizing
  • Image title, description, accessibility text and link
  • SVG support
  • Styles

Use Object

The Image component uses the com.adobe.cq.wcm.core.components.models.Image Sling Model as its Use-object.

Component Policy Configuration Properties

The following configuration properties are used:

  1. ./allowedRenditionWidths - defines the allowed renditions (as an integer array) that will be generated for the images rendered by this component; the actual size will be requested by the client device;
  2. ./jpegQuality - defines the image quality for JPEGs (0 lowest quality / size to 100 highest quality / size). Default value is 82.
  3. ./disableLazyLoading - if true, the lazy loading of images (loading only when the image is visible on the client device) is disabled.

Edit Dialog Properties

The following properties are written to JCR for this Image component and are expected to be available as Resource properties:

  1. ./fileReference property or file child node - will store either a reference to the image file, or the image file
  2. ./isDecorative - if set to true, then the image will be ignored by assistive technology
  3. ./alt - defines the value of the HTML alt attribute (not needed if ./isDecorative is set to true)
  4. ./linkURL - allows defining a URL to which the image will link to
  5. ./jcr:title - defines the value of the HTML title attribute or the value of the caption, depending on the value of ./displayPopupTitle
  6. ./displayPopupTitle - if set to true it will render the value of the ./jcr:title property through the HTML title attribute, otherwise a caption will be rendered

Extending from This Component

  1. In case you overwrite the image's HTL script, make sure the necessary attributes for the JavaScript loading script are contained in the markup at the right position (see section below).
  2. In case your own component does not only render an image but does also renders something else, use the following approach:
  3. resourceSuperType should be set to core/wcm/components/image/v1/image (to make sure the image rendering servlet is being used)
  4. Your HTL script should include the image markup via <div class="cmp-image" data-sly-include="image.html"></div>
  5. You derived component should reset cq:htmlTags
  6. You component's dialog should overwrite the dialog fully from the image component via sling:hideResource="true" on the node cq:dialog/content/items/image

URL Formats

The images are loaded through the com.adobe.cq.wcm.core.components.internal.servlets.AdaptiveImageServlet, therefore their URLs have the following patterns:



Client Libraries

The component provides a core.wcm.components.image.v2 client library category that contains a recommended base CSS styling and JavaScript component. It should be added to a relevant site client library using the embed property.

It also provides a core.wcm.components.image.v2.editor editor client library category that includes JavaScript handling for dialog interaction. It is already included by its edit dialog.

BEM Description

BLOCK cmp-image
    ELEMENT cmp-image__link
    ELEMENT cmp-image__image
    ELEMENT cmp-image__title

JavaScript Data Attribute Bindings

Apply a data-cmp-is="image" attribute to the wrapper block to enable initialization of the JavaScript component.

The following attributes can be added to the same element to provide options:

  1. data-cmp-lazy - if not false, indicates that the image should be rendered lazily.
  2. data-cmp-src - the image source. Can be a simple image source, or a URI template representation that can be variable expanded - useful for building an image configuration with an alternative width. Should contain a {.width} variable. e.g. '/path/to/image.coreimg{.width}.jpeg'
  3. data-cmp-widths - a comma-separated string of alternative image widths (in pixels). Populated with allowedRenditionWidths from the component's edit dialog.

A hook attribute from the following should be added to the corresponding element so that the JavaScript is able to target it:


The img and an optional image map should be placed inside a noscript element with the data-cmp-hook-image="noscript" attribute. They will be inserted into the DOM by the JavaScript component.

To allow lazy loading it is expected that the data-cmp-lazy and data-cmp-src options are supplied.

It is possible to configure the JavaScript component such that the most appropriate image url is built and applied to the img. The most appropriate width being the one which is at least as wide as the image's container. The data-cmp-widths option must be provided with more than one width, as well as the data-cmp-src option, with a URI template representation of the source.

To allow responsive recalculation of image map areas, a data-cmp-relcoords attribute should be added to each map area. The coordinates are represented as comma-separated decimal percentages:

    <area shape="rect" coords="0,0,10,10" data-cmp-relcoords="0,0,0.5,0.5" href="">


SVG MIME-types are supported, but have some specific handling. Alternative smart image widths defined at the component policy dialog are ignored for SVG images, with Image#getWidths returning an empty array. In addition, SVG image types have a more limited set of editing options available in the AEM inline image editor. The lazy loading feature is still supported for SVG images.
