Issue with Thumbnail View: thumbnails of png files not showed

[Dalai]

These files seem to be in the OneDrive folder, and are marked with a green checkmark. Not sure if that checkmark means they're offline or to be automatically synched, but that's probably the reason why the thumbnails aren't shown. For TC to be able to create thumbnails it needs to read the complete file - if that file is not stored locally or automatically downloaded on request, there's no way to create a thumbnail. This shouldn't depend on the file type, meaning that files like JPGs, GIFs and so on should also be affected.

UPDATE: PNG thumbnails only show in certain folders apparently. I had them shown in the work folder I was using (on my D: drive) but they still don't display on the original c:\...\Pictures\Samsung Gallery\DCIM\Screenshots folder where they go by default.

Are you sure the TAG-HEUR... file is actually downloaded to your onedrive folder, and it is not just in the sky?

I'd consider this a bug, not a configuration issue, since PNGs display properly with a clean .ini file. Just not in all dirs.
Most unusual...

Hello, I have exactly the same issue described above as well. I am running Total Commander (x64) 11.02 on Windows 11. Anyone managed to fix that?

Thanks

Hi all,

I found that I have the issue of thumbnails not showing ONLY for .png files AND within my OneDrive Pictures' directory, otherwise it works perfectly.

Do you guys think it may be related to the fact that MS is using reparse points for the OneDrive directory content on local storage?

ref.: https://en.wikipedia.org/wiki/NTFS_reparse_point#OneDrive

I found it by running this PowerShell command:

Code: Select all

Get-Item 'C:\Users\<username>\OneDrive\Pictures\*' -Force | Format-Table Name,Attributes

It produces an output similar to this:

Code: Select all

Name                                                         Attributes
----                                                         ----------
Camera Roll                           ReadOnly, Directory, ReparsePoint
Picture.jpg                                       Archive, ReparsePoint

Hoping it can help fixing it.

Thank you
Jonathan

Maybe the png files are only available online? I don't have this problem here, png files have thumbnails also in the OneDrive folder.

I can confirm what Jonathanpoulin stated, thumbnails do not show "ONLY for .png files AND within my OneDrive Pictures' directory" (anywhere in OneDrive, not just Pictures). I can put that png anywhere else and it will show a thumbnail. I should mention that ALL my files are "Always available on this device", none are cloud-only. (Disk space is cheap nowadays!) Could there be a diff in TC code due to localization??

Does the Explorer show thumbnails there?

[gunterotto]

Yes indeed.

If you have any Lister plugins installed, you can force Total Commander to load the png thumbnails from Explorer:
Configuration - Options - Thumbnails
Change the content of the edit box behind "Get from lister plugins for:" from
*.*
to
*.* | *.png
This way Lister plugins will not be used to extract png thumbnails, so TC should get them the same way as Explorer.

If this also doesn't work, change this string back to *.* and then install a Lister plugin like Imagine which can extract png files, and move it to the top of the lister plugins.

Hi, I'm from Thailand (I use google translate)
I've found a solution.
Download "IrfanView" and install it.
https://www.irfanview.com/

on Total Commander
Go to Options > Edit/View.
Press the Configure internal viewer... button.
On the Multimedia tab
Check "Use Irfanview/Xnview to load graphics other than BMP"
Set Path to i_view64.exe (c:\Program Files\IrfanView\i_view64.exe or i_view32.exe)

P.S. I have tried IrfanView as a lister plugin, but it didn't work.

I appreciate the suggestions. I may try some of the workarounds but, as long as Total Commander's "Quick View" keeps working for PNGs it's not such a big deal. My phones and cameras all shoot JPGs so I'm good for now, thanks.

The plot thickens. Apparently the same issue occurs with JPEG files as with PNG. Even if I take the same JPG image and copy it as a JPEG, Total Commander does not show a thumbnail. Again, this only happens in OneDrive. Please see image...

I have now checked this in the debugger:
1. For jpg files, Total Commander extracts the thumbnail stored within the image file by itself. This also works in the OneDrive folder.
2. For jpeg and png files, Total Commander calls the OLE function IThumbnailProvider->GetThumbnail when there are no Lister plugins to handle jpeg.
This works for files outside of the OneDrive folder, but inside it returns a strange error code 0x8004B205.
There are almost no results for this code (put in double quotes) on Google, except for "WTS_E_EXTRACTIONPENDING".
This seems to indicate that Windows postponed or cancelled the loading of that thumbnail.
Unfortunately there doesn't seem to be a parameter for IThumbnailProvider->GetThumbnail to force-load the thumbnail.

So your options are:
1. Install a Lister plugin which can extract thumbnails
or
2. Install Irfanview and set the path to it in the Lister's configuration.

Christian,

1. For jpg files, Total Commander extracts the thumbnail [...]
2. For jpeg [...] files, Total Commander calls the OLE function [...]

Totally off-topic for this issue, but why does TC handle JPG and JPEG files differently? Aren't they exactly the same format, just a different extension?

The default file type list for: "Internal thumbnails from images" (ThumbGdiplusTypes) is: *.jpg *.dng *.arw *.crw *.cr2 *.cr3 *.nef *.orf *.pef *.raf *.rw2
Maybe adding *.jpeg to that list solves the problem - and if it does, then *.jpeg should be added to TC's default list.
