Tech Mastery: Deep Dives into AEM, Cloud Technologies, AI Innovations, and Advanced Marketing Strate

We are using the image renditions to display the images for different devices in Adobe Experience Manager(AEM).

The HTML5 Adaptive image is used as shown below to display the images for different devices.

<img src="/content/dam/Albin/Untitled.jpg" srcset="/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png 1x,/content/dam/Albin/Untitled.jpg" alt="Sample Image">

/content/dam/Albin/Untitled.jpg - Original image
/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png - Rendition for 1x devices.

If the image is first accessed from the mobile devices then Untitled.jpg folder is created to cache the renditions image(rendition images will be matched for mobile devices) - /content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png

While the image is getting accessed from desktop browsers then dispatcher will try to return the folder Untitled.jpg as image(/content/dam/Albin/Untitled.jpg - original image will be matched for desktop browsers) so the image link will be broken in browser.

In other hand, if the image is first accessed from desktop browser then dispatcher caches Untitled.jpg as image. The subsequent request to the renditions image will not find the images in dispatcher cache so the image will be retrieved from publisher for rendering(rendition images will not be cached in this scenario as untitled.jpg is created as a image).

How to create different renditions for the Image in AEM/Adobe CQ5?

While uploading the images to DAM,Adobe Experience Manager(AEM) will create renditions of an image that include different sizes of the same image.This can be helpful when we need to create thumbnails or smaller views of large, high-resolution images.



We can configure the DAM Update Asset workflow to create the different renditions.

• Login to http://localhost:4502/etc/workflow/models/dam/update_asset.html
• In the workflow model select the thumbnail creation step and edit, in the process tab of the step we can add custom rendition values.
• Save the workflow

How to use HTML5 adaptive image in AEM/Adobe CQ5?

This post will explain how to use HTML5 adaptive image in Adobe Experience Manager(AEM)

The srcset attribute in HTML5 <img> element, allows us to specify different images for varying viewport widths and pixel densities. This allows us to load a larger image for new high resolution devices while displaying lower resolution images for others

<img src="image-src.png" srcset="image-1x.png 1x, image-2x.png 2x,image-3x.png 3x, image-4x.png 4x">

The width also can be specified to select the images.

<img src="small.jpg" srcset="medium.jpg 1000w, large.jpg 2000w" alt="Sample Image">
While uploading the images to DAM, Adobe CQ5 will create renditions of an image that include different sizes of the same image.This can be helpful when we need to create thumbnails or smaller views of large, high-resolution images.


The original or different rendition images can be used in HTML5 Adaptive image to display the images based on pixel density of the device,  browser will serve the image based on the resolution of the client.
