This is because I work on RAW. Thus there is no such case for me that
JPG exists in KPA and RAW should be found.
There are at least two places to get the information regarding this feature:
- Right click on the "File version search regexp:" or "Original file
replacementtext:" and select "What's this?"
- The manual that is available in Khelpcenter and as PDF/HTML from KDE docs
Seems that this is not clear enough currently and all the help in
improving these is appreciated.

I optimistically introduced the workflows chapter to describe
different workflows for different needs. Currently there is only one
and another (panorama workflow) in the works. So if you or anyone else
is interested in writing a flow, I'll be just happy to include it.

The newly found image goes to the top of the stack (IIRC). I don't
think there is any way to have the specific image automatically on the
top.

The prefix should also changed. Following example should handle the
case you describe above properly. However, combining this with your
other renaming convention will also have to be figured out. BTW for
testing purposes I suggest you set up a test directory with a few
images only and start KPA with -c <test-dir> parameter. This way it'll
take only a few seconds to see whether the config works or not.
Search regex: crw_([0-9]*)\.crw
Replace text: img_\1.jpg
This will change both the prefix and suffix from the existing file and
use whatever is between the parentheses in the middle. Thus when a new
file crw_1234.crw is found it will be changed to img_1234.jpg. And if
this JPG file is found in KPA DB, autostacking will occur.

Yes, I have inspected the KHelpCenter both from GUI and
workflows.docbook files installed. (Systemwide 4.2 from Dominik's PPA
repository and GIT version from my own compile.) Now the question is,
how does the reference disappear in your version.
