public Bitmap getBitmap(String fileName)
    {
        Bitmap bkBitmap = null;
        try {
                 FileConnection fconn = (FileConnection)Connector.open("file:///SDCard/Themes/"+fileName );
                 InputStream input = null;
                 input = fconn.openInputStream();     
                 int available = 0;
                 available = input.available();
                 int fSz = (int)fconn.fileSize();
                 byte[] data = new byte[fSz];            
                 input.read(data, 0, fSz);
                 EncodedImage image = EncodedImage.createEncodedImage(data,0,data.length);
                 bkBitmap = image.getBitmap();               
            }
        catch(Exception e)
            {
