I would like to show a GIF image on a website but i found that the animation is not working as the browser caches the GIF image after first load. Here is a PHP workaround by adding the current timestamp to the image src url.

<img src="https://eureka.ykyuen.info/example.gif?v=<?php echo Date("Y.m.d.G.i.s"); ?>" />

 

Done =)
