Updating a picture without page reload

Question

How would I go about updating an image that gets updated on a server every couple of seconds with out the user having to hit the refresh button, my first guess was ajax but

Answer 1

It seems there is something wrong with your Perl script. Trying to access the image by the URL should return an image anyway. It should return binary data and not a script. You should also set the Content-type header of the response to image/gif. Verify if it indeed returns binary data before trying to fix your JavaScript code.
