you can write buffered image to some public web space and provide src to that in img tag
provide src as servlet and output the image directly from the servlet

Example from BalusC blog

Here is a sample program taken from this post. It works fine.

<%@page import="java.awt.image.BufferedImage"%>
<%@page import="javax.imageio.ImageIO"%>
<%@page import="java.io.*"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<%
BufferedImage bImage = ImageIO.read(new File("/home/visruth/Desktop/Visruth.jpg"));//give the path of an image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write( bImage, "jpg", baos );
baos.flush();
byte[] imageInByteArray = baos.toByteArray();
baos.close();
String b64 = javax.xml.bind.DatatypeConverter.printBase64Binary(imageInByteArray);
%>

<div>
    <p>As of v6, Java SE provides JAXB</p>
    <img src="data:image/jpg;base64, <%=b64%>" alt="Visruth.jpg not found" />
</div>          
</body>
