[#1]

@tushargu@adobe.com @karmakar@adobe.com @carltonr@adobe.com

Request for Feature Enhancement (RFE) Summary:	Publish assets to the preview server
Use-case:	The requirement is to build an EDAM where all the assets reside. A key requirement for image management is the ability to expose an image for internal preview by other users/systems, without exposing the image publicly.
Current/Experienced Behavior:	Currently, there is no way to publish assets to the preview server for Assets customer.
Improved/Expected Behavior:	We would expect there to be an OOTB way to directly publish assets to the preview server.
Environment Details (AEM version/service pack, any other specifics if applicable):	Adobe Experience Manager as a Cloud Service
Customer-name/Organization name:	Starbucks
Screenshot (if applicable):
Code package (if applicable):

@Ankita-Das 

Thanks for proposing this idea.

This has been reported to the engineering under the internal reference ASSETS-41886. The product team will triage this request to verify feasibility based on the prioritization model. This post will be updated according to the Jira status.

After examining the source code under /libs/, I discovered that the deployment of the asset is deliberately disabled for reasons I cannot explain.
To enable these feature, Adobe developers should make the following changes because the /lib/ is read only from the perspective of the external developers:

1. Turn to show Preview radio in "Manage Publication" wizard
   Path: /libs/dam/gui/content/commons/assetmanagepublicationwizard/jcr:content/body/items/form/items/wizard/items/optionsstep/items/fixedColumnContainer/items/fixedColumn/items/destinationfieldset/items/destination/items/preview
   remove property: granite:hidden
2. Remove explicit hiding of the Preview radio in JavaScript
   File: /libs/dam/gui/coral/components/admin/managepublication/clientlibs/assetmanagepublication/js/managepublication.js
   Remove lines:
   662: // Hiding preview destination for assets
   663: var PREVIEW_DESTINATION_SELECTOR = DESTINATION_FIELD_SELECTOR + " coral-radio[value=\"preview\"]";
   664: $(PREVIEW_DESTINATION_SELECTOR).hide();
