Hi Asutosh. I am using AEM6.5.7. and you are correct those option are available inside Assets>Files directories. But the download and at to collection function in missing inside Assets > Templates folder

But the same setup didn't work for the URL. this.value["#image"].href = "https://upload.wikimedia.org/wikipedia/commons/thumb/8/8f/SAP-Logo.svg/320px-SAP-Logo.svg.png"

thank Mayank . the Base64data work. this.value["#image"].value = "BASE64DATA"

 Is anyone know how to enable download and add to collection button when you selected multiple files in author environment.Currently those 2 button is available in Brand Portal, but not in Author environment.see the screenshot below. Is there any configuration in author to enable those option ?  

Want to know how to dynamically call  the image source/path on certain conditions in form designer.Currently I setup [image field] in the document. Wondering how I can use javascript to call / add the image into the image field . I have tried to use the code below on [form:ready] this.value["#image"...
