There are many approaches you can take. Depends on what level of reusability of your components you want to achieve and details of input format (never seen NewsML...). If input is XML with data and images intermixed, use fragment extractor. If input is XML, one way is to write serializer which takes input XML with base64 encoded image and outputs image. It can also convert image from tiff to png (using some Java image manipulation library). If input is not XML, then you should write reader, which will read base64, decode it, and write image as output (converting as necessary). Vadim > or is their any easier/better way.
