Hi,

You can use class cl_wd_runtime_services method attach_file_to_response.

In the onAction of button get the image data and pass to the method:

  cl_wd_runtime_services=>attach_file_to_response(

      i_filename  =    <file_name>

      i_content   =    <file_data>

      i_mime_type = '<MIME>' )

Or you can simple use Filedownload UI. For reference check this wiki: http://wiki.sdn.sap.com/wiki/display/WDABAP/Upload+and+Download+files+in+Webdynpro+ABAP

Hope this helps u.,
