How To Remove Burstly Image Cache?

How can I display the latest version of an image when the image is saved in the cache?

  • I'm trying to figure out how I can display the latest version of an Image that is re-uploaded without having the user have to empty their cache. Typing "www." in the address also doesn't seem to help. There must be a simple solution to this. (Also, I am using timthumb with this: http://www.darrenhoyt.com/2008/04/02/timthumb-php-script-released/.)

  • Answer:

    Add a parameter to the URL. 'flower.jpg?v=123' will cause a client to grab a new version and the server will ignore the parameter. Keep track of the version number (123 in this example) and keep it consistent to take advantage of the user's cache, and increment the version number when the image has changed and you want them to grab the new version.

This can also be accomplished on the server side by adjusting the HTTP Expires response header, or by using ETags:  http://en.wikipedia.org/wiki/HTTP_ETag

You can do it using etags (did not see that in the code) or the if-modified-since header (support is there in timthumbs). The function you are looking for is probably: show_cache_file
