GIMP with the G'MIC plugins.

Found it. Thanks. http://gmic.eu/gimp.shtml
Very complicated. Maybe too complicated.
My Gimp is version 2.4.7

Have installed GMIC but have not figured out how to texture yet.

Welcome to the G'MIC-Qt for GIMP Setup Wizard
This will install G'MIC-Qt for GIMP version 2.4.3 on your computer.
C:\Users\jf\AppData\Roaming\GIMP\2.10\plug-ins\gmic_gimp_qt\platforms


Sorted by "Installation Date" the plugins are installed to Gimp 2.4.7.
Xtns - Plug-In Browser - shows the many GMIC plugins installed today
Gimp File - Preferences - Folders - Plug-Ins

The installed GMIC plugins appear to be recognized by Gimp 2.4.7.
Now comes the complicated part of how to texture any given JPEG image.
