  Is it possible to prevent a certain image in my page from being cached? I have an image that is updated between loads but when it's cached the browser keep producing the original image. :- (
  

  
  

  
  Any ideas?
  

  
  Thanks

  You have a number of options

  
  
  1. Configure IIS to automatically expire the content (see http://www.developerfusion.com/show/228/)
     
  2. Create some javascript to add a random value on the end of the src tag... ie src="images/theimage.gif?randomvalue"
     
  3. point the src parameter to a server-side script such as php/asp, which adds an Expires header, and then outputs the image
