Hi Kundan, we attached the image in Workfront. Is that not possible for your instance? If you can do that, then you can use the URL from that image to load to the custom form. Getting the right URL for the image is a little tricky - you have to load the image then go to document details then right click on the download button and copy link address. You can't use the amazon link as it will expire.
Thanks for answering this @Stacey_Robertson . I believe this kind of option should be available, especially in case of custom form. Even missing template for custom form like similar dashboard template.
