Understanding CustomUrlAvatar
The CustomUrlAvatar extension is a Review Board extension that adds a system-wide URL for user images. By configuring the extension, administrators can define a URL pattern that will be used to fetch user images from an internal gravatar service or any other custom URL. This allows for a seamless integration of personalized user avatars within Review Board.
Configuration Example
Let’s take a look at a configuration example utilizing the CustomUrlAvatar extension:
#
https://images.mylocalcompany.org/?user={user}&s={size}
In this example, the variables {user} and {size} are used to fill in the corresponding values for each user and the desired size. These variables can be omitted if not needed, allowing for a more flexible URL configuration.
