@noriega3 The ngx_http_image_filter_module is not one of the statically or dynamically loaded modules included in the nginx-buildpack. You can see those listed in the documentation here: https://docs.cloudfoundry.org/buildpacks/nginx/index.html#loading-modules.

This means that you would need to include this module in your own modules directory in your source code for this to work for your application.

@noriega3 We are closing this due to lack of activity. It seems that --with-http_image_filter_module is a nginx module that can be loaded by some user configuration.

If there are other reasons why this module cannot be loaded, or other concerns please re-open this.
