Python-slack-sdk: How to edit/update image an image attachment from a message? Is this possible?

Description

I have an image that changes in real time, basically I take snapshots from time to time, and I need to be able to send that image on a channel with the changes. Send the first image in a message and then just replace the image attached by a new updated image from time to time. I don't wanna clutter a channel with multiple images, I want one single message with image then the image attached changes, Is this possible? How? Thanks!

Unfortunately, it's not possible to realize the user experience by uploading several files and calling chat.update. Let me share two alternative solutions. I know these solutions are not fully equivalent to your original plan. But I hope this is helpful to you.

1: Remote files' preview_image

If you're fine with using the remote files API, you can use file blocks for displaying a remote file's display_image in a message this way. Here is the sample code. The main points are:

  • files.remote.add with versioned external_ids and preview_image (simply relying on file id is also fine)
  • chat.update with the new external_Id

2: Unfurling public image files

Probably, this is not suitable for your use case but if you can make the image files public, uploading those files somewhere and using chat.unfurl may be an option.
