<blockquote type="cite">Since it happens to the same images on all
systems, it seems to me the problem is with the image (nice image,
by the way :-) )
<br>
Are they all RAW-images, with (supposedly) embedded
jpg-thumbnails? Could it be that the embedded preview is broken,
some way or another? If "rebuild thumbnails" makes a thumbnail of
png and jpg, and copies the embedded preview of RAW, then that
explains why you don't see anything (assuming that is the
problem).

More on the "invisible images".<br>
<br>
I found a difference between the "invisible" and "visible" images.
Perhaps this can help to solve it.<br>
<br>
I selected "Table" view to see all the images.<br>
Then the right tab, "metadata".<br>
Then the images that behave normally on "thumbnail" view, do not
have a dedicated paragraph "Embedded Thumbnail". In my box, their
metadata starts on "Global Positioning System". Now if I change
something on them with the editor and save as another file, these
files have an "Embedded Thumbnail" paragraph, with the fields:<br>
<br>
- Compression JPEG(old-style)<br>
- JPEG Interchange....<br>
- JPEG Interchange....<br>
<br>
Now here is the weird thing. The images that do are "invisible" on
"Thumbnail" view, also have this paragraph. So, I guess at some
point they were edited as well. But the content is different:<br>
<br>
- Compression JPEG(old-style)<br>
- JPEG Interchange....<br>
- JPEG Interchange....<br>
<b>- Resolution Unit inch</b><b><br>
</b><b>- X-Resolution 300</b><b><br>
</b><b>- Y-Resolution 300</b><br>
<br>
These last three lines are only on those images that are not seen by
"Thumbnail" view. I use my boxes with metric units, not inches. I do
not know if this can be part of the problem. Perhaps they were
edited by some of the previous versions of Digikam and got these
extra lines that may be not "compatible" today (I use DK4.10.0). If
this is the case, then this can be happening to other users as well.
I am just speculating at this point but perhaps it helps to diagnose
the cause.<br>
<br>
I hope this helps to find a better solution than editing each image
in ShowPhoto... <br>
<br>
Many thanks!<br>
