Maybe Not What I Expect?

I was pleased to discover this mod, however, perhaps it's not meant to provide the functionality I'm looking for.

I don't want my image nodes to be cached so when a person goes to view one, the image on the server must be fetched. This is because I'm uploading a stream of images and therefore the image is always changing.

I activated this mod and when I go view an image, I still get an old version.

Let me know if I'm not using it right or expecting functionality it isn't meant to provide.
