I have some PDF files which have their covers in their first page. When I'm in Thumbnails view in DOpus, I would like to see the covers. How is this possible?
Are you on 32-bit of 64-bit Windows?
Do any PDFs show any thumbnails?
Which PDF software/viewers do you have installed?
I have foxit reader installed and I see only the foxit reader pdf icon on pdf files in thumbnails view.
DOpus 32bit USB portable on Windows 7 32bit.
From what I remember, Foxit doesn't generate thumbnails.
Adobe Reader should do them on 32-bit Windows.
Any plugins for DOpus that can do this?
Not that I know of. It's up to the system's PDF viewer(s) to provide thumbnails for PDF files.
The easiest way to get PDFs to show thumbnails is to install a recent version of Adobe Reader. You don't have to use it, just install it.
You will also find several discussions of "PDF" and "thumbnails" hereabouts. It is a regular topic, although perhaps less so given recent versions of Reader.
Sorry, but I don't see pdf thumbnails here either.
I'm on Vista32 using Nitro PDF with Adobe Reader X installed after I uninstalled older versions of Adobe Reader .
I later installed Adobe Reader X to better handle web pdfs.
I had sent in a camera for repair and paid for a FedEx shipping label.
The pdf containing the label failed to generate using just Nitro PDF, although other pdfs loaded just fine from urls.
After installing Adobe Reader X, the pdf containing the label then loaded.
I really haven't used thumbnails to view pdfs in the past as I've preferred details mode and the viewer pane.
I do have many pdf tool and equipment manuals that have an interesting first page cover.
I simply add this post as info to this discussion.
Microsoft XPS docs display thumbnails just fine.
I have Use Shell Extraction for Formats Opus Does Not Understand Checked.
What happened to the camera? Did they fix it successfully?
Don't know yet Jon !
It's a Minolta A1 with a failed CCD. A year ago an affected unit would have been rapaired for free.
Mine wasn't affected until Jan 1 . 
They are the only US Minolta authorized repair service.

The FedEx tracking info says it's stiil on the truck, delayed by a snowstorm.
They should get it Monday. It's been well protected, lens and LCD are near perfect.
I just can't let it go with all the features it had, and then there is the battery investment ... .
Well let us know how it goes!
I'm guessing you don't see them in Explorer either?
PDF-viewing software (well, Adobe's at least, but I suspect the love for the alternatives is more because they're "not Adobe" more than anything else) seems to be the most fragile, poorly written stuff on the planet (well, excluding video codecs, anyway). Having more than one PDF viewer on the system at once makes things even more complicated as they fight over filetype registration.
I wish people would just stop using PDF altogether; it'd make life so much easier. Paper is dead!

Oh so true. Having added a PDF reader to your system, it helps to play around with the default "Open with" application. Choose the wrong one, and even if you do have Reader installed, you won't see thumbnails.
Fortunately, DoPus gives you plenty of control over context menus and click operations.
For various reason, I have Acrobat (version 7, because it is good at batch shrinking files), PDF Converter Pro (because it is good at web integration and editing recent PDF files) and Reader (because it does thumbnails). PDFs are associated with Reader (still on version 9). Other applications are set to use particular programmes to open PDF files.
Thumbnails show just fine in DoPus and Explorer.
What would you suggest as an alternative? I still print to paper and need page layouts.
More important I need to be able to index, search and display within >130,000 PDF files.
Happy to use an alternative. But what?
Saved web pages are a nightmare to file and index.
Thankyou very much michaelkenward ,
I'm still happy not being able to view thumbnails as my doubleclick opens Nitro pdf
and the viewer pane gives me a very nice Adobe Reader X which opens full screen to the full Dopus Viewer.
I'll play around some both in windows and in Dopus filetypes though and see if I can get the thumbnails working here.
I don't want to get off topic, but I almost posted a kind of related thread a few weeks ago.
I decided not to at the time as it broke password security, but really ....
I found a pdf download of the manual for my Minolta Camera. If Minolta ever had one, I can't find it.
It was a zip file containing three pdfs dividing an exact copy of my original Minolta A1 manual into three arbitrary parts.
Naturally, I wanted to combine these files into one pdf. Nitro pdf told me they were Password Protected and it could not proceed.
I needed a free pdf password remover. I found one that is command line and was originally intended as an addon for Ghostscript.
I can't find the exact Sourceforge download, but it can still be downloaded at numerous third paty sites found by a google search.
It is called simply, Freeware PDF Unlocker. After installed it is intended to function by Drag and Drop to a desktop icon.
One drags a locked pdf to the icon and an unlocked pdf is generated in the same folder as the locked pdf.
It works very well, although it substituted one font on me ; I'll never notice.
It was then very easy to reconbine the three parts and form one contiguous pdf Minolta A1 camera manual !
Better yet, it's easy to make a button in Dopus for it.
For the simple password protection I encountered:
cd "C:\Program Files\Freeware PDF Unlocker"
"C:\Program Files\Freeware PDF Unlocker\unlockpdf.cmd" {filepath}
The Dos window is really kind of fun in this case.
There is also a pdf manual in the program files install directory.

Faced with the death of my own thumbnails, recovering from problems due to Nuance's insane approach to "activation" of its software, I decided to make the leap to Adobe Reader X while I was at it.
This seems to have introduced a possibly superior way of dealing with this issue.
In the Preferences area, on the "General" tab, there is a button "Select Default PDF Handler". This isn't quite the same as the "associate" feature of earlier versions.
I know there are people who have an aversion to the bloated stuff that Adobe puts out, bug you don't have to use it for other things. It just makes the integration with Windows a bit easier.
Pressing that button instantly restored my thumbnails.

Thanks much for that info ! I tried it and it didn't work here.
You had me going though and I started trying all kinds of things including uninstalling both Nitro and Adobe Reader and starting over by installing Adobe Reader.
I even tried installing Adobe Reader 9 to no avail. By this point I was getting a little irritated and then realized that Windows did not have a filetype association for a pdf extension.
I then defined Adobe Reader to be the default program to open pdf.
Voila!!! The thumbnails began appearing at once. Almost done.
I then went to DOpus Filetypes and defined a left dbl-click to open a pdf in Nitro.
I still have thumbnails of pdfs.
Your saga does not surprise me. It echoes my own frustrating experiences with getting PDF thumbnails to work.
I lost them this time because I mistakenly made something else the default viewer when reinstalling some software.
The common theme in any resolution seems to be the need to have Adobe Reader installed. Anything after version 8 seems to do the trick, although the newer the better is my experience.
Other software just does not seem to be able to enable PDF thumbnails. Even the latest version of the software I use, Nuance's PDF Creator – think of it a poor man's Acrobat – lacks this ability.
My guess is that different PDF tools do different things to the registry, which is why there isn't a simple "press this button and voila" trick.
At least, if anyone turns up here with similar issues there should be enough clues for them to work from.
