ᐅ Detecting Leaky Windows Using Thermal Imaging

In winter, we constantly have wet window panes despite indoor humidity levels of 40-50%.
We always ventilate regularly with short cross-ventilation.

I took some thermographic images during winter and would like to get an opinion from someone familiar with this.

Unfortunately, I only took one picture from outside.

What kind of house? What exactly about the windows? How is the house insulated? Room temperature? Outside temperature? Outdoor humidity? Ventilation habits? Is it only the panes that are damp? In which rooms?
