High resolution images for retina capable devices

Most Apple laptops, iPads, iPhones, and high-end Android devices are HiDPI, or retina capable, meaning that they can display very high resolution images in a small space and make them look really good. In version 10.5+, you can enable display of higher resolution images when a retina-capable device is detected. Currently, higher resolution images will only be displayed for news carousel images and thumbnails that show on sections in grid layout.

1. Go to the Admin panel: Content section > Files and images page.
2. Find the Page header and image settings section.
3. Select the checkbox Display higher resolution images on desktop to display higher resolution images when a retina-capable device is detected. By default this setting is checked.
4. Select the checkbox Display higher resolution images on mobile to display higher resolution images when a retina-capable mobile device is detected. By default this setting is unchecked.
5. Click Save.

If you opt for high resolution images over intranet performance, enable the retina options. If you want to optimize performance over quality images, disable the retina options.

Image browser settings

The image browser, or Choose Image window, displays when you go to add an image to the page body, page header or thumbnail of an intranet page. The image browser allows users to select images from galleries on the intranet. Users can pick from galleries recommended by administrators, and if enabled, they can search through any of the galleries that they have view permissions on. Users can also use photos from the free online photo library Unsplash.

Admins choose Recommended galleries

Administrators can select certain photo galleries to appear in the Recommended galleries section of the image browser. The Recommended galleries section appears above All galleries, and can feature curated galleries of top-notch images that you want your users to be using on their pages.

To set a gallery as a Recommended gallery:

1. Go into edit mode on the gallery page.
2. Select the checkbox Set as a recommended gallery under the page title.
3. Click Save on the right side of the page.

Now the gallery will appear in the Recommended galleries section of the image browser when a user adds an image to a page.

Page header and gallery settings

Administrators can choose whether users can edit page header backgrounds and whether users can add images to page headers. If users are not permitted to add images to page headers, color gradient backgrounds are available for them to select.

To change page header settings:

1. Go to the Admin panel: Content section > Files and images page.
2. Find the Page header and image settings section.
3. To allow users to edit page header backgrounds, select the checkbox Allow editing of page header backgrounds.
4. To allow users to use images as page header backgrounds, select the checkbox Allow images to be used as page header backgrounds.
5. Click Save.

Administrators can also choose whether users can add images to a page from any gallery that they have permission to view.

To change gallery settings:

1. Go to the Admin panel: Content section > Files and images page.
2. Find the Page header and image settings.
3. To allow users to select images from all galleries, select the checkbox Allow images to be selected from photo galleries when adding images to pages.
4. Click Save.

Enable/Disable Unsplash integration

The Unsplash integration allows users to add free high-quality professional photos from the Unsplash website to intranet pages. The Unsplash integration is enabled by default. Unsplash images can be searched and imported from the Unsplash tab in the image browser window. 

To disable or re-enable the Unsplash integration, go to the Admin panel: Integrations section > Unsplash page. Change the toggle to OFF to disable the Unsplash integration, or ON to re-enable the integration.

If Unsplash is disabled, any Unsplash images that were previously added to content are not affected.

Self-hosted clients

In order to fetch images from Unsplash, the webserver should have outbound access to api.unsplash.com over https (tcp/443). If you are a self-hosted client, you will need to allow this outbound connection from your webserver through the firewall.

To validate this open a powershell window on the webserver and try:

PS C:\Users\sid> Test-NetConnection api.unsplash.com -Port 443

ComputerName : api.unsplash.com
RemoteAddress : 199.232.93.181
RemotePort : 443
InterfaceAlias : Wi-Fi
SourceAddress : 172.16.12.4
TcpTestSucceeded : True
