There have been several times where images disappear from articles. They look like this:

They are not even saved in the Images section in Guide, so I have to go find the image on my computer again, or in some cases re-do a screenshot.
Any idea why this is happening? Is there a way to prevent this?
Hello Kevin,
Please note that RoboHelp is a tool from Adobe and we unfortunately cannot troubleshoot it or guarantee how that tool works.
But it seems that RoboHelp is not correctly pushing the images into the Help Center, and that is why the images do not get authenticated and disappear after 3-4 days.
I would suggest that you add manually the images directly into Zendesk, and not using RoboHelp.
