Etude, If you can't see my plant picture in my first post then I'm not sure what the problem is.
At least it does not sound like something you are doing wrong.
Here's the link to the actual picture you posted the link to above.

Thanks Dis-member, it's my wife's plant and yes it is growing in just water.
Nice part is you can start it from just a single stem and in a short time have your whole house filled with them if you like.
In my case it is where I get replacments for the ones I plant in dirt then forget to water :-)
The picture was just me playing with HDR photograpy.
You take a dark and a light photo of the same thing and merge them (that was the only time I really ever attempted it but it came out quite nicely)
Here are the two originals.
