Connecting To Flickr
Once you have added Flickr to your page, navigate to the component 'Settings' then enter your username in the Username field to connect.
Ensure your Flickr Profile is Visible
If your username is not found when entering it into the Username field, your Flickr profile may not be visible. Your profile must be visible in search in order to connect it to your website. You can enable visibility by logging into your Flickr account and ensuring the "Hide your profile from public searches" setting is disabled from your privacy settings.
You can also control the public visibility of your Flickr photos. Please see Flickr's support article for instructions on how to manage this.
Please see Flickr's article on managing your Privacy Settings for further assistance with this.
