Images can really bring your bot to life... as long as they're the right size. If your files are too big or awkwardly sized, it can make for a slow and ugly user experience. Here are a few top tips to help you when creating visuals for your bot!
An image message part can consist of either a jpg, gif or png. Images must not exceed 1024 ×1024 px or 1 MB. Unfortunately, animated gifs are currently not supported on Teams.
A carousel is often used to contain the main topics and top strands of your conversation which we refer to as the Main Menu. A carousel can have a maximum of 10 cards.
Each card has to have an image and a title. We also suggest that it has a subtitle and a button.
The title and the subtitle can have a maximum of 80 characters each.
Each card can have a maximum of 6 buttons.
A carousel image should have an aspect ratio of 16:9 and not be more than 420px wide.
