When you work with your team in Slack, you may need to collaborate on files that you’ve created in other services from time to time. Add files to your workspace to share and discuss them in Slack.
Drag and drop up to ten files into the message field, or click the Paper clip icon next to the message field and choose from where to add a file.
Include a message about the file(s) if you like. If you don’t need to include a message, you can upload the file immediately by holding the Shift key as you drag and drop it into Slack.
Send the message.
Open a channel or direct message (DM).
To add up to ten photos, tap the image gallery icon. To add a file, tap the file with clip icon to add a file that has already been shared in Slack, then tap Add a file to upload a file from your device.
Add a message about your file(s) if you like.
Tap the paper plane icon to send.

In conversations, Slack will include a preview of the file as part of your message. If it's an image file, the preview will display inline as long as it's smaller than 11,000 pixels on the longest side or less than 45 million pixels in total. Bear in mind that Microsoft Office files that are larger than 50 MB will not display a preview.
