more help please!!!

i was able to call the  camera using the palmphotocapture function. then save 
it. when i tried to check the photoH, it is not null so i guess i got the 
image.  

first problem, when i add the image into an album, i get an error.

next, because i don't want the image to be seen on the photos on palm, i 
skipped the problem above.

second problem, i can't display the image. i am saving the image on the stream. 
i retrieve it using the palmphotoopenImage. i checked the handle, it isn't 
null. so again, i guess i got the photo. but when i tried to display it using 
the PalmPhotoDisplayImage, nothing happend.

can you show me what i am doing wrong?

here is  my function for displaying the image:

void OpenImage()
{
    UInt32    density = 0;

    /** 4 testing **/
    Char                    *msg = "";
   
    /** for retrieval **/
    PalmPhotoHandle         photoH = NULL;
    PalmPhotoFileLocation    fileLocation;
    PalmPhotoCreateParam    createParam;
   
    /** for display **/
    PalmPhotoDisplayParam    displayParam;
     RectangleType            displayRect;
     Coord                    width, height;
    WinHandle                winH;


    /** photo image info **/
    PalmPhotoImageInfo        imageInfo;
    BitmapType                *tmpbitmapP = NULL;

    InfoMsg(tempimageDescription);
   
    // setup callframes
    //MemSet(&fileLocation, sizeof(PalmPhotoFileLocation), 0);
   
    MemSet( &createParam, sizeof(PalmPhotoCreateParam), 0 );
   
    createParam.fileLocation.fileLocationType = palmPhotoStreamLocation;
    createParam.fileLocation.file.StreamFile.type = 'Foto';    //BLOGAppType;   
 //'Foto';
    createParam.fileLocation.file.StreamFile.creator = 'Foto';    
//BLOGCreator;    //'Foto';
    StrCopy(createParam.fileLocation.file.StreamFile.name, 
"Photo_101105_001.jpg");        
   
    /** capture photo **/
    photoH = PalmPhotoOpenImageV2(PhotoLibRefNum, &createParam.fileLocation);
   
    //err = PalmPhotoGetImageInfo(PhotoLibRefNum, photoH, &imageInfo);
   
    err = PalmPhotoGetImageInfo(PhotoLibRefNum, photoH, &createParam.imageInfo);
   
    if ((!err) && (photoH))
    {
        InfoMsg("image successfully opened");
   
        WinScreenGetAttribute(winScreenDensity, &density);        
//MemSet(&displayParam, sizeof(PalmPhotoDisplayParam), 0);
       
        width = (createParam.imageInfo.width + 1) >> 1;
        height = (createParam.imageInfo.height + 1) >> 1;        //width = 160; 
   height = 120;
               
        if(density == kDensityDouble)
            winH = WinCreateOffscreenWindow(width, height, nativeFormat, &err);
        else
            winH = WinCreateOffscreenWindow(width, height, genericFormat, &err);
       
        if (!err)
        {
            displayRect.topLeft.x = 0;
            displayRect.topLeft.y = 0;
           
           
            if(density == kDensityDouble)
            {
                displayRect.extent.x = width;
                displayRect.extent.y = height;
            }
            else
            {
                displayRect.extent.x = createParam.imageInfo.width;
                displayRect.extent.y = createParam.imageInfo.height;
            }
           

            //displayParam.winH = WinCreateOffscreenWindow(width, height, 
nativeFormat, &err);
            displayParam.winH = winH;
            displayParam.rect = displayRect;
            displayParam.displayCallback = NULL;
            displayParam.userDataP = NULL;
           
            err = PalmPhotoDisplayImage(PhotoLibRefNum, photoH, &displayParam);
           
            if (err)
                GenerateErrorMsg(err);
            //WinDeleteWindow(displayParam.winH, true);   

        }
    }
         
}


thanks a lot!
