Users can currently send & share files such as images, PDFs and videos in Google Chat messages and use the Shared tab to access all conversation-related artifacts including files, links and media. However, only one image can be uploaded in a single Chat message on web at a time. 

To improve upon this functionality, provide a highly-requested feature, and match the mobile experience, we’re excited to announce that users can now upload and send up to 20 multimedia files (photos and videos) in one Chat message. Dragging and dropping multimedia files into the compose bar from your desktop is also supported. 

• Administrateurs : There is no admin control for this feature. 
• Utilisateurs finaux :
  An error message will show if a user exceeds size limits or uploads unsupported file combinations. Visit the Help Center to learn more about l'envoi et le partage de fichiers dans les messages Google Chat.
