NAS selection help - picture browsing is essential?

[vladio2000]

Picture browsing is my priority, my wife would like just to grab an android phone and just browse pictures, videos, etc. Key factor is also price, a 2 bay device should be fine. The device needs to be able to be configured without an online server to be present ( got a Netgear stora, that cannot be configured, as it is trying to access a netgear server which is off ). So far, I found qnap TS230 as a viable option, please chip in with experience, bad or good about it or any similar device.
Thanks in advance,
