[Koha] Link to external patron picture

Just upgraded to 3.14 With every new version I'm installing I have to manually change some files to allow accessing the patron pictures which are already there on our school system. Is there a way that would allow me to use an link to an external picture (instead of uploading the pictures to Koha or changing code) ? Any setting to do that I have not found so far?
