The so called nomacs portable is not portable at all- it writes to Windows registry (HKEY_CURRENT_USER\Software\nomacs)...

This is not true. I just checked it on a clean virtual machine. All settings are written to the settings.nfo which is contained in the nomacs portable folder. If you delete this file - nomacs will fall back to the registry.

All by nomacs; I tested on a clean machine in a sandboxed environment and I have never used IrfanView, Picasa, or Photoshop before.

Hmm. I just tested v3.4.0 in Sandboxie with RegFromApp and no Registry entries were created apart from the standard MuiCache ones. I wonder if this has to do with the testing environment.
