The Core Component Image Component is an adaptive image component.

Usage

The Image Component features adaptive image selection and responsive behavior with lazy loading for the page visitor and easy image placement for the content author.

The content author can use the edit dialog to edit the image asset such as applying a crop or rotating the image.

The image widths and additional settings can be defined by the template author in the design dialog. The content editor can upload or select assets in the configure dialog.

Version and Compatibility

The current version of the Image Component is v3, which was introduced with release 2.18.0 of the Core Components in February 2022, and is described in this document.

The following table details all supported versions of the component, the AEM versions with which the versions of the component are compatible, and links to documentation for previous versions.

Component Version	AEM 6.4	AEM 6.5	AEM 6.5 LTS	AEM as a Cloud Service
v3	-	Compatible	Compatible	Compatible
v2	Compatible	Compatible	-	Compatible
v1	Compatible	Compatible	-	Compatible

For more information about Core Component versions and releases, see the document Core Components Versions.

Responsive Features

The Image Component comes with robust responsive features ready right out of the box. At the page template level, the design dialog can be used to define the default widths of the image asset. The Image Component automatically loads the correct width to display depending on the size of the browser window. As the window is resized, the Image Component dynamically loads the correct image size on the fly. There is no need for component developers to worry about defining custom media queries since the Image Component is already optimized to load your content.

In addition, the Image Component supports lazy loading to defer loading of the actual image asset until it is visible in the browser, increasing the responsiveness of your pages.

TIP

By default, the Image Component is powered by the Adaptive Image Servlet. See Adaptive Image Servlet for details on how it works.

Differences with v2

Unlike version 2 of the Image Component, version 3 uses browser-native responsiveness. This means that it provides the browser with a set of sources for an image for different widths and the browser will pick the best.

Most of the time, browsers prefer to locally downsize a larger width to fit a smaller viewport instead of fetching the smaller width image from the server. This is expected and why the Image Component should not be used for art direction (different images/crops for different viewports).

Please see the technical documentation of the Image Component for more information.

Dynamic Media Support

The Image Component (as of release 2.13.0) supports Dynamic Media assets. When enabled, these features offer the ability to add Dynamic Media image assets with a simple drag-and-drop or via the assets browser just as you would any other image. In addition, image modifiers, image presets, and smart crops are also supported.

Your web experiences built with Core Components can feature rich, Sensei-powered, robust, high-performance, cross-platform Dynamic Media Image capabilities.

Remote Assets Support

The Image Component (as of release 2.23.2) supports remote assets. Once configured, you can select assets from a remote service for your image component.

SVG Support

Scalable Vector Graphics (SVG) are supported by the Image Component.

Drag-and-drop of an SVG asset from DAM and upload of an SVG file uploaded from a local file system are both supported.
The original SVG file is streamed (transformations are skipped).
For an SVG image, the “smart images” and the “smart sizes” are set to an empty array in the image model.

Security

For security reasons, the original SVG is never called directly by the Image Editor. It is called through <img src="path-to-component">. This prevents the browser from executing any scripts embedded in the SVG file.

Technical Details

The latest technical documentation about the Image Component can be found on GitHub.

Further details about developing Core Components can be found in the Core Components developer documentation.

The Image Component supports schema.org microdata.

Edit Dialog

The edit dialog allows the content author to crop and zoom the image.

Depending on if you have the Dynamic Media enabled or Remote Assets Support is enabled, the options available for editing images differ.

Standard Asset Editing

If you are editing standard AEM assets, you can click the Edit icon in the context menu of the image component.

Image Component's edit dialog

Start Crop

Selecting this option opens a drop-down for pre-defined crop proportions.
- Choose the option Remove Crop to display the original asset.
Once a crop option is selected, use the blue handles to size the crop on the image.
Rotate Right

Use this option to rotate the image 90° to the right (clockwise).
Reset Zoom

If the image has already been zoomed, use this option to reset the zoom level.
Open Zoom Slider

Use this option to display a slider to control the zoom level of the image.

The in-place editor can also be used to modify the image. Due to space limitations, only basic options are available in-line. For full edit options, use the full-screen mode.

Image in-place edit options

NOTE

Image edit operations are not supported for GIF images. Any such changes made in edit mode to GIFs is not persisted.

Dynamic Media Asset Editing

If you have Dynamic Media features enabled, editing of the image itself must be performed in the assets console.

Configure Dialog

The image component offers a configure dialog where the image itself is defined along with its description and basic properties.

Asset Tab

Asset tab of the Image Component's configure dialog

Inherit featured image from page - This option uses the featured image of the linked page or the featured image of the current page if the image is not linked.
Image asset - This is automatically populated if Inherit featured image from page is selected. Deselect to manually define the image by setting the following options.
- Drop an asset from the asset browser or tap the browse option so you can upload from a local file system.
- Tap or click Clear to de-select the currently selected image.
- Tap or click Pick to open the asset browser so you can select an image.
  - If Remote Asserts Support is enabled, you have multiple options for picking an asset:
    - Local selects from the local AEM asset library.
    - Remote selects from a Dynamic Media library outside of your AEM instance.
- Tap or click Edit to manage the renditions of the asset in the Asset Editor.
Alternative text for accessibility - This field allows you to define a description of the image for visually impaired users.
- Inherit alternative text from page - This option uses the alternative description of the linked asset value of the dc:description metadata in DAM or of the current page if no asset is linked.
Don’t provide an alternative text - Marks the image to be ignored by assistive technologies like screen readers for cases where the image is purely decorative or otherwise convey no additional information to the page.

Metadata Tab

Metadata tab of the Image Component's configure dialog

Preset Type - This defines the types of image presets available, either Image Preset or Smart Crop, and is only available when Dynamic Media features are enabled.
- Image Preset - When Preset Type of Image Preset is selected, the drop-down Image Preset is available, allowing selection from the available Dynamic Media presets. This is only available if presets are defined for the selected asset.
- Smart Crop - When Preset Type of Smart Crop is selected, the drop-down Rendition is available, allowing selection from the available renditions of the selected asset. This is only available if renditions are defined for the selected asset.
- Image Modifiers - Additional Dynamic Media image serving commands can be defined here separated by &, regardless of which Preset Type is selected.
Caption - Additional information about the image, displayed below the image by default.
- Get caption from DAM - When checked the image’s caption text is populated with the value of the dc:title metadata in DAM.
- Display caption as pop-up - When checked, the caption is not displayed below the image, but as a pop-up displayed by some browsers when hovering over the image.
Link - Link the image to another resource.
- Use the selection dialog to link to another AEM resource.
- If not linking to an AEM resource, enter the absolute URL. Non-solute URLs are interpreted as relative to AEM.
- Open link in new tab - This option opens the link in a new browser window.
ID - This option lets you control the unique identifier of the component in the HTML and in the Data Layer.
- If left blank, a unique ID is automatically generated for you and can be found by inspecting the resulting page.
- If an ID is specified, it is the responsibility of the author to make sure that it is unique.
- Changing the ID can have an impact on CSS, JS, and Data Layer tracking.

TIP

Smart Crop and Image Preset are mutually exclusive options. If an author must use an image preset along with a Smart Crop rendition, the author must use the Image Modifiers to manually add presets.

Styles Tab

Styles tab of the edit dialog of Image Component

The Image Component supports the AEM Style System.

Use the drop-down to select the styles that you want to apply to the component. Selections made in the edit dialog have the same effect as those chosen from the component toolbar.

Styles must be configured for this component in the design dialog for the drop-down menu to be available.

Design Dialog

Main Tab
