I’ve seen the comments about image preview changing in MM4, and would like to see it in action before upgrading. Is there a demo site somewhere?

Easy viewing of images is essential for us, MM3 is working fine but of course would like the shiny new 4.0!

Thanks,

Tac

Hey @tacman, we have two sites

1. [demo.mattermost.com](http://demo.mattermost.com): This runs on the latest release build, in this case 4.0.2
2. [pre-release.mattermost.com](http://pre-release.mattermost.com): This runs on the latest build, updated nightly. Might be unstable between releases.

Let me know if you have any questions – and also if you have any feedback about the changes!

Thanks! I was looking at [demo.mattermost.org](http://demo.mattermost.org), forgot about the .com.
