You say you converted the projects from CHM to WebHelp but you don't really convert, you simply generate a different output. Thus the way you have phrased it makes me wonder quite what you did, did you create a new project?
When you say the folders do not show the images, do you mean the source folders or the output folders? I'm guessing the former.
Are the images in the same folder as the topic or in a folder with nothing but images? If the latter, add a topic to that folder and then apply an Exclude tag to the topic.

You are correct, for "conversion" I changed the primary layout to WebHelp. To allow for a merged WebHelp project I created a "blank" parent project and changed the output location of each child project to the "mergedProjects" subfolders. I also had to reset the external links.
The source folders physically contain the JPG files, but they are not listed in the RH Project Manager panel. The JPG files are not physically in the output folders after a generate.
The images are in the same folders as the topics where they are used.
As a test, I changed the name of one folder. Yes, the images were then listed. I closed RH and restarted with the same project. The images are again not listed in that folder.
Yes, the project is on my loacl drive. The path isn't long; it's "C:\TMSHelp\Projects\WebAdmin".
I have been replacing the images because the UI style has changed. The older images did have spaces, but the my new ones do not. Regardless, all the images would disappear, spaces or not.
No, I had not tried deleting the CPD file. So, I did it just now and reopened the project. Magic, my images are all listed in all the folders!
Thank you very much. I have noticed the "delete the CPD file" suggestion in other posts. I will try that in the future when odd things happen.
