Image with same path doesn’t show up due to cache in browsers

Browsers are designed to think that Images with same name don’t change rapidly so regularly. This creates a problem in some cases where you have to reuse a specific name Or a specific location for a system.

One such case can be a social network which is designed in a way where the profile images are always:

http://www.mysite.com/users/images/user123/profile.jpg

Now, on changing this image, sometimes browsers don’t clear cache and thus show the last image. In Order to solve this, use a random number at the end of the image location and you will be able to see that image. as browsers will not cache it.

http://www.mysite.com/users/images/user123/profile.jpg?123

One method that I used is:

$stamp = time();
$imageLocation  = 'http://www.mysite.com/users/images/user123/profile.jpg?'.$stamp
echo $imageLocation

This should work.

Think Lamp » cache
