Displaying byte array as image; base64 data URI doesn't work above 32KB in IE

Question

I have a image as byte[] in my bean. User can upload image using <h:inputFile/>. As soon as user clicks upload the image should be displayed in the page(Should not be saved in DB/Folder). I tried using Base64 convertion but in IE it's displaying only 32KB size image. Below is my xhtml code.
<h:form id="signatureform" enctype="multipart/form-data"> <h:inputFile id="inputFile" label="file1" value="#{bean.part}"/> <h:commandButton id="upButton" type="submit" action="#{bean.uploadSignature}" value="Upload" styleClass="commandButton"> </h:commandButton> </h:form>
<h:graphicImage url="data:image/jpg;base64,#{bean.encodedImage}" width="275px" height="75px"></h:graphicImage>
My Java code is

private String encodedImage ;
private Part part;
//getters and setters 
public String uploadSignature() throws IOException {

    InputStream inputStream = null;
    try {
        inputStream = part.getInputStream();
        encodedImage = new String(Base64.encode(IOUtils.toByteArray(inputStream)));
    } catch (Exception e) {

    } finally {
        if (inputStream != null) {
            inputStream.close();
        }
    }
    return SUCCESS;
}

I have tried with <a4j:mediaOutput/> but no help. Please help me to resolve it.

Finall i was able to display my Image in IE. My requirement was to display an image in 275px *75px. For this requirement i resized my image in Java and displayed in the Web page. When i resized my image and converted to Base64 string it became less than 32kb. I tried with 12MB image and it worked fine :). Below is my code.

        BufferedImage imBuff = ImageIO.read(inputStream);
        BufferedImage resizedImg = resize(imBuff, 275, 75);
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        ImageIO.write(resizedImg, "jpg", os);
        encodedImage = new String(Base64.encode(os.toByteArray()));

private  BufferedImage resize(BufferedImage image, int newWidth, int newHeight) {
        int currentWidth = image.getWidth();
        int currentHeight = image.getHeight();
        BufferedImage newImage = new BufferedImage(newWidth, newHeight, image.getType());
        Graphics2D graphics2d = newImage.createGraphics();
        graphics2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
                RenderingHints.VALUE_INTERPOLATION_BILINEAR);
        graphics2d.drawImage(image, 0, 0, newWidth, newHeight, 0, 0,
                currentWidth, currentHeight, null);
        graphics2d.dispose();
        return newImage;
    }

Hope this will help others who are trying to display a big image in small size in the web page.
