The slack export was created using the slack-advanced-exporter, maybe some png library missing or something :frowning:

Are any of the images you expected to be imported actually missing when you look at the messages in the Mattermost channels? Those lines can be caused simply by file uploads which are not images in the Slack import - in which case they are fine, and completely expected.

Yea turns out the image are actually there. Thanks for the response.
