Enabling preview for web-optimized image

Hi,

I have a requirement to enable previewing of WebP images (*.webp) in AEM On-Premise, specifically in the author instance. Essentially, when an image is uploaded, you should be able to see its preview. Currently, we’re unable to preview WebP images even though the WebP MIME type has been added to the OSGi configuration.

I understand that AEM On-Prem does not natively support WebP images, but my requirement is specifically to preview the image in the author instance.

Please note that my use case applies only to AEM On-Premise and does not involve AEM as a Cloud Service or acquiring a Dynamic Media/Scene7 license for smart imaging capabilities.

The use case is strictly to preview the image once uploaded to the DAM. If this works, we can configure ImageMagick to generate the necessary renditions in WebP format. I have already reviewed the following suggestions.

Please confirm if you're using AEM Cloud or AEM On-Prem version.

Ensure that the MIME type is registered in:

Apache Sling Mime Type Service
Apache Jackrabbit Oak Blob Data Store

And create a custom handler or override the existing preview handler for WebP images by extending the DAM AssetProcessor service.

Thanks for your reply. I have made changes only to the Mime Type configuration so far. Let me check the Oak Blob Data Store, as you suggested.

Could you please explain more about the need to introduce a custom handler or override the existing DAM AssetProcessor service?

I'm not able to locate this config "Apache Jackrabbit Oak Blob Data Store". Can you share the screenshot?

A scenario for this could be that a dispatcher filtering out and limiting rendering of that specific file.

Check your dispatcher, does it allow webp files?

/filters
{
  /0001 { /type "allow" /url ".*\\.webp" }
  /0002 { /type "deny" /url "/etc/.*" }
  ...
}

Thank you for your response. The issue is specific to the author instance, not the publish instance. I want to enable the preview of WebP images on an AEM 6.5 on-premise instance.
