Refreshing an image

[php_guy]

Hello all,

 

Is there a way to force the user's browser to refresh an image on every visit to the page? (regardless of their Internet settings or cache settings)?

 

E.g. I have a page that links an image (via IMG SRC tag) but this image is updated every once in awhile. I want the user's browser to always have the latest copy of it when they visit the page

 

Thanks!

I'm trying to remember but it goes something like this.  you append a ?var=some_random_number to the image src

 

<img src="yourpic.jpg?time=<?php echo time(); ?>"/>

 

Should force the browser to get the newest image
