Currently I am working on a website registration page and I want a new user to select a default avatar from a given list if they have not uploaded a profile image while they are registering. I am using drupal 7 so avatar selection module is not compatible with this version so can you kindly suggest me some other way out
Using the Media module you can allow users to select images from a library or upload there own which sounds like what you want. I assume that functionality would apply to the user image, but I have not tried that. I know it works for image fields you create so you'll have to take a look, but either way seems like media module has the basis of what you want.
