I think we need to dig a bit deeper on this one. You said:
The result was that only new images were published.
if you are only talking about the official "Publish" part, this is spot on. Only new images should be published as that's how publishing actually is intended to work. Only things that are new or updated.
But you go on to say:
All previous content images - created prior to the RH 2015 update, no longer displayed the images.
And this leads me to conclude that you aren't talking about publishing per se, but instead are referring to the actual output. The generated content.
For the moment, I'm going to focus only on the images. No sense in trying to tackle a word document issue.
Let's start by asking this. Where or how exactly are you attempting to view the content? Immediately after generating output by clicking the View Result button from RoboHelp? After uploading files to a Web Server?
Can you share a screen capture of a page where the images aren't appearing? And can you share the HTML code for the same page?
You also said:
Someone also attempted to open the project file in a latest version of RH and the files appear to be corrupted.
Sorry, but more information is needed on this. Perhaps some screen shots?
Once I received the actual files from the client, I was able to resolve the problem by importing the old Snippet pod files.
Here are the steps that I gave the client after successfully importing the Snippet pod files:
Here are the steps to importing the files:
- Go to the Snippet Pod and click on Import.
- You can select the hts files that are missing from within your project files.
