How to use images from drawable folder as contributor avatars?

[DanyGee]

Here is my contributors.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <contributor
        name="Dany Gee"
        contribution="blah blah blah"
        image="@drawable/about_profile_dany"
        link="" />

    <contributor
         name="Franczeska Piórko"
         contribution="blah blah blah"
         image="@drawable/about_profile_frania"
         link="" />

 </resources>

Those image="@drawable/about_profile_frania" do not work.

Remote URL's work as expected: image="https://avatars3.githubusercontent.com/u/26818551?v=3&s=300"

What am I missing here? :thinking:
