Question

Hello i have a php file that is dynamically creating images. Basically its adding a text on theimg . Im calling them like this in the html without problems

<img src="img.php?session=<?php echo $session; ?>" />
<img src="img.php?session=<?php echo $session; ?>" />

Now if the image on the server change and i call this again from the html the image doesnt change, i have to do a full page refresh in order to see the new image.
[EDIT] Ive also noticed that it works ok on Chrome. I have this problem at firefox only, its like igonring the <meta http-equiv="Cache-Control" content="no-cache/>

The solution I adopted is the following one.

var ts = Math.round((new Date()).getTime() / 1000);
<img src="img.php?session=<?php echo $session; ?>&time=' + ts + '" />
