Adding Embedded Image to report at runtime

Hi,
I am trying to add an Embedded Image into my report design at runtime through my Java Class. I have successfully added it to the report design. But i am not able to use this image anywhere in the report . It throws an error telling that the "name is invalid". Below is my code.
 
 
 public static void _addEmbeddedImage(ReportDesignHandle designHandle) throws IOException{ 
 EmbeddedImage embeddedImage = null; 
 try{ 
 embeddedImage = new EmbeddedImage(); 
 embeddedImage.setName("logo.jpg"); 
 embeddedImage.setType(DesignChoiceConstants.IMAGE_TYPE_IMAGE_JPEG); 
 embeddedImage.setData(_getImadeAsByteArr()); 
 designHandle.addImage(embeddedImage); 
 }catch(Exception e){ 
 throw new IOException("Error while adding Embedded Image into the Report Design"+e.getMessage()); 
 } 
 } 
 public static byte[] _getImadeAsByteArr()throws IOException{ 
 String encodedImage = ""; 
 byte[] bytes = null; 
 try{ 
 File imageFile = new File("C:/BIRT/Resources/logo.jpg"); 
 FileInputStream inputStream = new FileInputStream(imageFile); 
 bytes = new byte[(int)imageFile.length()]; 
 } 
 catch(Exception e){ 
 throw new IOException("Error while parsing Image File @_getEncodedString .. Error: "+e.getMessage()); 
 } 
 return bytes; 
 }
 
 
 
 public static void _addNewImage(URequestContext ctxt,IReportRunnable design)throws Exception{ 
 Object pageContents = null; 
 Object imageContent = null; 
 ReportDesignHandle designHandle = null; 
 SlotHandle masterPageHandle = null; 
 SlotHandle headerHandle = null; 
 
 ImageHandle imageHandle = null; 
 EmbeddedImageHandle embeddedImageHandle = null; 
 ElementFactory factory = null; 
 try { 
 designHandle = (ReportDesignHandle)design.getDesignHandle(); 
 factory = designHandle.getElementFactory(); 
 _addEmbeddedImage(designHandle); 
 //designHandle.save(); 
 masterPageHandle = designHandle.getMasterPages(); 
 Iterator masterPageIter = masterPageHandle.iterator(); 
 while(masterPageIter.hasNext()){ 
 SimpleMasterPageHandle pageHandle = (SimpleMasterPageHandle)masterPageIter.next(); 
 headerHandle = pageHandle.getPageHeader(); 
 Iterator headerSlotIter = headerHandle.iterator(); 
 if(!headerSlotIter.hasNext()){ 
 List imagesList = designHandle.getAllImages(); 
 Iterator imagesIter = imagesList.iterator(); 
 while(imagesIter.hasNext()){ 
 imageContent = imagesIter.next(); 
 if(imageContent instanceof EmbeddedImageHandle){ 
 embeddedImageHandle = (EmbeddedImageHandle)imageContent; 
 imageHandle = factory.newImage(null); 
 imageHandle.setSource(DesignChoiceConstants.IMAGE_REF_TYPE_EMBED); 
 headerHandle.add(imageHandle); 
 } 
 } 
 // headerHandle.add(imageHandle, headerHandle.getSlotID()); 
 } 
 } 
 } catch (Exception e) { 
 logger.debug("Error while adding Embedded Image to report design.. "+e.getMessage()); 
 } 
 finally{ 
 designHandle.save(); 
 designHandle.close(); 
 } 
 }
 
 
Any help would really be appreciated.
