Martin asked if tkimg package is installed. It is installed. I suspect
if it were not, then png files would also fail.
==================
bgee@main2:~$ rpm -qa | grep -i tkimg
tkimg-1.4.16-4.fc42.x86_64

Wookey - Therion is apparently compiled against libjpeg-turbo.

===================
The error message is coming from a TCL program. TCL is an interpreted
script - not an ELF image. I think the concept of "compiled against
library xxx" does not apply here. Something in that script is loading
libjpeg, but I have no idea what it is or where it is called.
Looking through the source code - I see the error message is generated
at line 737 in me_imgs.tcl. Looking at the code around that line, I do
not see anything suggestive. The message is triggered when an object
named $imgid is null (line 735), which means some earlier code is not
recognizing the jpg file as valid. Or perhaps not even trying to load it??
Looking at package descriptions - openjpeg is intended for JPEG 2000
formats. libjpeg-turbo is intended for general jpeg handling.

It appears that xTherion will no longer load ANY jpg file.
The system is Fedora 42. Therion is 6.3.4+dev, compiled back in
April. I have several jpeg libraries installed:
root@main2:~# rpm -qa | grep jpeg
libjpeg-turbo-3.1.0-2.fc42.x86_64
openjpeg-2.5.3-6.fc42.x86_64
turbojpeg-3.1.0-2.fc42.x86_64
openjpeg-tools-2.5.3-6.fc42.x86_64
libjpeg-turbo-utils-3.1.0-2.fc42.x86_64
libjpeg-turbo-devel-3.1.0-2.fc42.x86_64
openjpeg-devel-2.5.3-6.fc42.x86_64
jpeginfo-1.7.1-6.fc42.x86_64
jpegoptim-1.5.5-6.fc42.x86_64
mjpegtools-libs-2.2.1-8.fc42.x86_64
OK. Just checked on Debian 13 (stable released last week) and therion
will load jpegs OK there.
In case it helps:
therion
6.3.4-2 amd64 Cave surveying - 2D
and 3D drawing software
libjpeg-turbo-progs
1:2.1.5-4 amd64 Programs for
manipulating JPEG files
libjpeg62-turbo:amd64
1:2.1.5-4 amd64 libjpeg-turbo JPEG
runtime library
libturbojpeg0:amd64
1:2.1.5-4 amd64 TurboJPEG runtime
library - SIMD optimized
So your libjpeg-turbo is 3.x whilst I have 2.x. Maybe that's
significant? I think libjpeg-turbo and openjpeg are alternatives. Check
which therion is using on your system. Mine is linked against
libjpeg.so.62 which comes from libjpeg62-turbo
