Plugin Doesn't Allow Custom Content Directories

This plugin dosen’t seem to support custom WP CONTENT directories. wp-content is hardcoded in:

$avatar_src = get_site_url()."/wp-content/uploads/avatars/".$item_id."/".$avatar_img;

for example

I don’t use wp-content which means I’ll need to modify this plugin.
