Standing in a car park, I was able to successfully receive the images using a handheld 3 element 144 MHz Yagi antenna connected to a RTL-SDR USB dongle.
The dongle was connected to Windows-8 tablet using a USB OTG cable.
I was running SDR# to listen and record the FM audio on 145.800 MHz.
I had a LNA connected between the antenna and rtl-sdr but since the the downlink from the ISS was quite strong it was probably not required.
