[Bug 305104] New: Digikam does not show some jpg images in files

https://bugs.kde.org/show_bug.cgi?id=305104

            Bug ID: 305104
          Severity: grave
           Version: 2.5.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Digikam does not show some jpg  images in files
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Other
            Status: UNCONFIRMED
         Component: Thumbnails
           Product: digikam

I just noticed that not all .jpg images are shown in photo files although the
total number of images shown although the count in the tree view is correct.
The images had the suffix .JPG (Upper case) and when I manually renamed two of
them to .jpg (lower case) their thumbnails appeared.  I tried a batch rename of
all of them to .jpg but they still did not appear.  I have moved the images to
other files and they do not appear.

I have done re-scans and the images thumbnails do not appear.
I have checked permissions and they are the same as other (viewable) images
GwenView shows the images correctly.

This is a binary compatibility issue with digiKam KIO slave on your system :
It's typically a packaging problem with dependencies...

Update digiKam to last 2.8.0 and try again...

I have the same issue with Version 2.8.0.
I use the MYSQL database, in which alle the images are listed for the folder in
which I have the problem (with jpg and JPG extensions which corresponds to the
file name extension) . Also they are all present in the folder (as I see in a
terminal), but the files with JPG don't show up in the Album preview for this
folder

In other folders, where I have images with upper case JPG ending, the images
show up, so I don't know what's different in this specific folder.

I Use:
digikam/quantal uptodate 4:2.8.0-0ubuntu1
digikam-data/quantal uptodate 4:2.8.0-0ubuntu1
libkface-data/quantal uptodate 1.0~digikam2.8.0-0ubuntu1

Did you edit them with the digikam image editor, hiding the original?

(In reply to comment #3)
> Did you edit them with the digikam image editor, hiding the original?

I guess you are refering to the non-destructive image manipulation. I didn't
edit the picture.
I did some further test, an in a new image folder it is no problem to have
jpg/JPG files.
I guess there is something mixed up in the Database, also I could not find
differences in the images / imageinformation tables in the pictures showing up
or  not showing up. However, when I moved all images from the folder to another
place (on a terminal), and then back, the missing images reappeared. In the
"image" Table they have a new id
Still, I have the problem that I don't know if images in other folders are not
shown our found by refreshing.

I'm having the same problem with some JPG images not showing up in Digikam.
The images in question used to show up, because they have tags that I added
using Digikam.

If I check: Settings → Configure digiKam → Editing Images → Always show
original images, the missing images appear.  The Image HIstory bar shows a mess
of Derived Images and Identical Images that are neither derived nor identical.

Is there a pattern how to reproduce this situation? Do you remember how you saw
this first?

Unfortunately, I don't know when or how the problem started.  I just noticed
the images were missing in Thumbnails view, but I'm sure the problem went
unnoticed for awhile.

Have not see the problem lately and I have been working with local and
network files so I think the bug has been killed.

Thank You

The problem still exists with:
Qt: 4.8.6
KDE Development Platform: 4.14.9
digiKam: 4.6.0


by checking: Settings → Configure digiKam → Editing Images → Always show
original images, the missing images appear, as previously described.

I have the problem too. Interestigly, the "Table" view mode is not affected,
only thumbnails and preview.

The "versioning" sidebar also show some pictures with tons of "identical
images" that are not identical _at all_. Like an Aquarium image from Akademy
2015 daytrip is identical to a camp file from Randa.

Encountered this problem in digikam Version 3.5.0 with KDE 4.13.3 on Ubuntu
14.04.05 LTS.

Status of this bug is resolved as  FIXED in Version 4.0.0 but  Juraj #c11said
on 2015-07-13 15:53:34 UTC
that the problem still exists with digiKam: 4.6.0.

Any news about that?

How do I fix the "mess of Derived Images and Identical Images that are neither
derived nor identical"? Is this possible to do within digikam? Or do I have to
use a command line tool to remove the non identical images? And how do I do
that?

Thank you very much!

I did the following, awhile back, on linux.  Not sure what may have changed in
the interim, and I can't speak for non-linux platforms, so YMMV.  FIRST, BACK
UP YOUR DATABASE!

Make sure digikam is not running.  Go into digikam4.db using sqliteman and drop
and re-created the imagerelations table. Re-start digikam.  I don't remember if
there's a tool that you have to run manually, or if it runs automatically, but
it should recreate correct image relations.  May take awhile depending on the
size of your albums.

I hope this helps.  Please post your results for others.

Given I just **deleted** the database and started from scratch and still have
the issue, I would argue that the bug isn't fixed, it never was and it still
fully there as of Digikam 5.1

I forgot to say in my comment 13 that I encountered that problem in only one
album which is a folder synced with the Dropbox client after editing an image.

It looks like bug 323210 is a duplicate of this one, maybe someone with the
permission can set this and maybe also edit the summary of this bug to
something like “Digikam does not show some jpg images because assigned wrong
identical/derived images”.

What I tried to fix the problem:
I deleted the wrong data sets (I had 21 entries for one subject with different
objects, type 1 and the same objects also for another subject - 42 wrong
entries in total) and later cleared the table ImageRelations  - also with no
success. The images still have the wrong identical images assigned. The cleared
table is still empty. So these information has to be stored elsewhere - but
where? I couldn't find a corresponding XMP entry in these images with neither
exiv2 nor exiftool.

Tools -> Maintenance -> Sync Metadata and Database -> Sync direction: From
database to image metadata
seems to be useful, but in the settings no checkbox looks like the right one.
