Each birthday and work anniversary will be celebrated with an image. Matter provides three different options based on your preference. Options can be different or the same for birthdays and work anniversaries. For example, you can use the image URL library for birthdays and the custom image upload for work anniversaries.
Who can use this: Workspace Owners and Admins on the Basic plan and above, or on any plan during the free trial. Works the same for Slack and Microsoft Teams workspaces.
For an overview of the whole feature, read the Celebrations Guide.
Celebration Image Options
Matter Template: Matter's default option. If uploaded, the profile pictures from Slack and Microsoft Teams will be used in the celebration message. If not uploaded, the template will be truncated.
Custom Image Upload: This uploaded image will be used for all celebrations of the respective type. This is ideal for company-branded assets. It can be a PNG, a JPG, or an animated GIF.
Image URLs: Add up to 10 image URLs, including links to animated GIFs. Matter will randomly select when delivering the celebration. We recommend using Giphy.com when searching for celebration images.
Animated GIFs in celebrations
Yes, celebration images can be animated GIFs, with both Custom Image Upload and Image URLs. The GIF plays in the celebration message in Slack and Microsoft Teams.
Each image or GIF needs to be under 2MB. GIFs are the file type most likely to go over that limit, so if one is too big, shorten the loop or cut the number of frames.
Changing Celebration Images
Go to the Web App.
Go to Settings, then the Celebrations section.
In the respective Birthday and Work Anniversary section, select the dropdown under the Birthday Banner Experience and change to your preferred option.
Custom Image Upload: Image sizes need to be less than 2MB. Animated GIFs are supported.
Image URLs: Image sizes need to be less than 2MB. Animated GIFs are supported.
Click Save to finalize setting changes.
