Hi everyone? I need some help with doing away with the gravator option in buddypress and replacing it with a “upload photo” function that will be used as the gravator during registration. I come from Africa, Kenya to be specific and people here dont have or rather dont know what gravators are. My idea is to create a photo upload profile field during registration, then set that same uploaded photo as the default gravator instead of mystery man. Can somebody help with finding the path of the user,s uploaded photo so that I can use it to replace mystery man. And I am using xampp to develope the site locally installed on a local disk E.
