Image will not change on the Browser...Saving on the Tomcat Problem...HELP

Question

Hi,
I worte a Servlet project using JBuilder 7 and TOmcat 4. THis is basically what i am doing...
I am getting an image from database and saving it to a folder in tomcat and then displaying it on a browser.
This application is used by multiple users...
I am saving the Image in Tom-cat...C:\JBuilder7\jakarta-tomcat-4.0.3\webapps\examples\Image1.jpeg
I am also displaying the image from that folder. The problem is when i run the application,
I am seeing the same Image on the screen..Its creating the different Image file, but the image is the same.
If i do a refresh on the page then it displays the new saved Image...
Also, If i save the image on my local and then display it from my local it changes the images as I
click on a Image list...
Following is how it works when i save it and display it from my local, but if i run my application from
another computer i am not able to see any of the images....Because its on my local.
     fos = new FileOutputStream("C:/Image1.jpeg");
     <img src="file:///C|/Image1.jpeg" height="855" name="myimage" align="middle" style="position:absolute;">;
And this is how i am doing when i am saving to the tomcat....I am able to display it on another computer
but would not change the image...
fos = new FileOutputStream("../webapps/examples/Image1.jpeg");
<img src="../Image1.jpeg" height="855" name="myimage" align="middle" style="position:absolute;">;
Can some one please tell me what could be the Problem....
Any help will be greatly appreciated....Thanks...

The browser caches images so that it doesn't have to always download the same image for different pages.
You could:
1: Save the new image with a different name and dynamically change the name in the html.
2: Try setting the response headers to prevent the browser from caching the images.
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
