Yes, there's a bug in the handling of image objects in Dialogs in version 11.0.07... There's nothing to be done about it, unfortunately, except for downgrade to an earlier version where it worked correctly.
Thanks for your reply.
Is it possible that if we use the latest API documentation at http://help.adobe.com/livedocs/acrobat_sdk/11/Acrobat11_HTMLHelp/wwhelp/wwhimpl/js/html/ww help.htm?&accessible=true
and above issue can be fix ?
or we must have to wait for next release/patch from adobe ?
