thank you, I will try that!

Can I just replace files, will that not affect images that are already uploaded there?
No, you also have to run an upgrade script. See the upgrade instructions in the image_manager.txt file.

Upgrading IM will not and never touch existing images, everything remains like is was before the upgrade.
