Does anyone know how to use phpThumb?

I have a problem with the cache. When I replace an image with the same name and settings, my browser or maybe phpThumb will load the cached image instead of the new one.

I need to know how to delete a particular cache so that whenever I delete an image, I will also delete it's cache. Seems like the cached image name is hashed. I have no idea how to regenerate the hash.

For example, if I make an image :-
phpThumb.php?src=uploads/0018.jpg&wl=128&hp=128
It will generate a cache :-
phpThumb_cache_localhost_src9a75e89a946fe8806c4d99 765ef5e75d_par8ef1fff75b634c96b07a379e91bdfd22_dat 1152005649.jpeg

So, when I delete the image, I want to delete it's cached image as well but how do I get the hashed parameter?

You could try sending headers to not cache the images.

PHP Code:

header("Cache-Control: no-cache, must-revalidate");

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

Actually i already did. Because I did my site in Ajax, the page doesn't refresh. Therefore, the browser doesn't load the new image. How do I work around this?

Basically, the page will upload image, show it's progress, then display the image in a div tag. When you upload a new image, it will replace the one you uploaded previously but the new image won't load because it's showing the cached image.
