With the launch of our new admin vendors now have profile images. Currently we use the Gravatar image associated with your email, which is a global standard used on sites like Wordpress, news sites, etc.
If you don't already have one you can set a Gravatar here:
Be sure to use the email you have on file with DPD when setting up your Gravatar, otherwise we won't be able to pull it for use in your profile image.
We may add the ability to upload a picture directly to the profile in the future, but the profile image is a new thing so we were kinda just seeing who actually cared about it :)
