Collections are still a work in progress, but it correctly placed Jean de Florette and Manon of the Spring into a "Water of the Hills" collection automatically.
The easiest way to edit is from within the DMS GUI, just click on the poster, then click Edit as shown; you can also use the old way, by entering your DMS IP address in your web browser, like http://192.168.1.7:32080. Neither one allows uploading of local images yet, hopefully that will come. The PC web browser seems to offer more focused poster choices, but that can vary by title.
