How to populate an image in Adobe Interactive forms using webdynpro?

Hello,

     I'm trying to display an image on an Inetractive adobe form using webdynpro. Here is what I have done till now:

1. I have the image data in xstring format.

2. I have created an image field in form layout and binded it to the context attribute which i'm setting at runtime with the xstring format data.

Issue : the image is not getting populated on the form.

I have tried it using ABAP dictionary interface for an offline scenario and it's working fine. But for interactive scenario where I'm using xml schema based interface, I am not able to find any option to insert a graphic node as we do in case of ABAP based interface/form.

please suggest.

thanks,

Aniket
