When I upload a group of photos using a zip file, I notice that the zip file remains on the server in the 'large' folder after the files have been extracted. This wastes a lot of the available web server space.

Is it possible to get the zip file deleted on the server automatically after the files contained in it are unzipped and processed? Not everyone I allow to upload photos will be smart enough to drill into each album with file manager and delete the zip files left behind.

Thanks
