You need to to place the image effect file in a folder named `image_effects` and place that folder into the `plugins` folder. (in the root of your install)
You must never change anything in the `/zp-core/` folder.
it should actually read`%WEBPATH%/%USER_PLUGIN_FOLDER%/image_effects/bevel.js` to work in the `/plugins` folder (and does in the example `bevel.txt` I have). NEver put anything withn `/zp-core` unless you want to do it again on every update.

You must never change anything in the `/zp-core/` folder.
Some paths in the bevel.txt (and all other filters of that brand) pointed to the wrong folder:
/%WEBPATH%/%USER_IMAGE_EFFECTS%/
instead of
/%WEBPATH%/%ZP_EXTENSIONS%/%IMAGE_EFFECTS%/
Works perfect now!
