Thumbnail options in RoboHelp 2020

If your project was previously on a network drive and you were generating to a network drive, that could definitely lead to issues. The specific network setup and your connection to it can cause slowness and also micro-interruptions, which could mean files aren't generated to the right place (or aren't saved or only a partial file is saved). Additionally, network paths frequently can be extremely long, and long paths also prevent files saving - this is a Windows limitation, not an RH issue.

I personally always keep my project on my C drive and in a folder right off C, not inside the Documents folder. This prevents network issues and long path issues. If I need my output on a network location, I set up a publishing destination and use that to copy the output to the required place - there's much less chance of something going wrong when the only thing happening is copying files, and I believe the technology is designed to handle network dropouts better. (To back up my source files, I manually zip the entire project folder and copy the zip to a network location. )

I love all this detective work! You guys are great!

I was able to create a project on C:. It didn't make any difference in the thumbnail situation, but generating output is now a bazillion times faster, so that's a win. Plus for some reason, moving the project to C: solved my disappearing index problem (which I hadn't even brought up yet on this forum :).

I wondered whether the problem was with the skin (even though I've tried this with several fresh copies of Studio), so I created a new frameless preset and generated output using the Orange skin. I made sure to select Create Thumbnails for Images in the preset. Same result---no _th.png files in the output folder. This is the relevant code I see in the topic:

class="popup-image-thumbnail" src="../../assets/images/Login_screen.png" title="Log In Screen" data-rhwidget="Basic" data-popupimage="../../assets/images/Login_screen.png" width="613"

The first path looks like a hyperlink (blue and underlined). I also notice that when I use the Orange skin, the "X" button to close the pop-up looks right, unlike the problem I mentioned above with the "X" button and Studio.

@Amebr You might be on to something there. When testing this I did find I couldn't see an _th image and thought maybe I was looking in the wrong place. Then I generated with both options and used Beyond Compare to find the difference to ascertain where I should be looking.

Okay, random suggestion time. I was seeing the same problem with RH2019 just then. In the preset I selected a different skin and regenerated. And then I could see the _th suffix in the code. Changing back to the original skin now generates the _th suffixed images as expected. Maybe that will work for you as well. 🙂

This issue seems to be just you, that's what I am struggling with. It works for me.

Yes, \images was just shorthand for the full path. I did search for the _th.png files and nothing turned up. (I did see them once in the output \images subfolder, but I think I overwrote that subfolder in a subsequent test and they never came back.) For me, the two thumbnail options seem to be behaving the same way.

I just can't imagine that everyone is having this many problems with the Frameless layout (I haven't even posted about all of the issues I've run into because you've already spent so much time trying to help!). 

I appreciate all the suggestions, I really do. The issue is not corporate content, which I could easily eliminate; I'm pretty sure any external upload site will be blocked on my end. (I've been down this road before.)

I just discovered that Update 7 is available for me now, so I'm going to install that in the next day or so. Maybe if I start over, some of these issues will just go away. 

Perhaps you're running into network or path length problems. 

Can you create a test project somewhere like c:\test\project and generate to c:\test\output to rule out both network issues and path length?

Still getting the same results in a new project with one topic and one thumbnail, using a fresh Studio skin.

As much as I would love to send you my source files and see if you can figure out what's going on, I'm afraid my employer doesn't allow me to do that. I have SO many issues with RH 2020 that I might have to call Adobe Customer Support directly and hope they can walk me through some things. 

Thanks so much for all the time you've spent helping me with this!

Fresh copy of Studio skin, generated to a new output folder. Same result (missing "X").

I selected "Create Thumbnails for Images" and I don't get any _th files in the output \images folder. 

I've tried this with two different projects and I get the same results. 

The upgrade to RH 2020 and my attempts to produce Frameless output that functions correctly are beyond frustrating.
