We are using ImageVault 4.8 (or something like that). An editor was wondering how to update an image, would that even be possible?
ImageVault3 had a "Replace original" feature that came with a warning text that it didn't touch the formatted images based on the original. Looks like they removed the feature in 4. Can't find it in the manual or in my test instance.
That's correct. You are currently not able to replace an image as you could in ImageVault 3
Probably best to upload with different name anyway to clear all client cache
