Sending multimedia content and documents within chat conversations in Microsoft Teams
Yes, but it depends on which pictures are meant in Teams:
- Pictures in a meeting gallery: the number of participant videos or profile pictures shown can be changed. In a meeting, select View and then choose the Gallery size or Select max gallery size option to show 4, 9, 16, or 49 people at a time on desktop, depending on the meeting view and device support. Teams may still show fewer videos if bandwidth or device memory is low.
- Group chat image: the group chat image can be changed, but the display size is not described as user-adjustable. Teams supports uploading a custom image, with a maximum upload size of 4 MB.
- Pasted or attached images in chat/posts: there is no documented setting to manually control the preview size of pasted images. Teams determines the preview layout automatically.
- Teams Free app window: the desktop app window itself can be resized by dragging the pane edges or corners, which changes how content fits on screen, but this is not the same as directly resizing an individual picture.
