1. Whenever just one end of the car is elevated, it is recommended that you put wheel chocks on the low end. In this case the rear. Raising just one side could potentially cause the car to roll --- in this case "roll backward". Again, the chocks are meant for the JUST IN CASE situations.
2. Looking at the pic, the wheel on the ramp is actually barely at the flat top (horizontal plane) of the ramp. This appears to be very prone to rolling.
3. When using ramps, always ensure the wheel is cradled by the horizontal top section.
4. In lieu of wood, I find that it was faster for me to jack the car and slide the ramps under the wheels. Of course, I have many jacks (factory, regular, low profile, high-reach jacks...)
