It's not impossible, actually I thought you're talking about megabytes of data
(you could transfer megs but it would take a very long time). 20k isn't a big
image, even though the data throughput is quite low with motes. All you have to
do is chop the video into smaller chunks and reconstruct in the rx side. Search
the list for posts about maximizing data payload size and continue from there.

First of all, if it's a digital picture you mean by "image", a TinyOS
network is far from suitable for transferring large amounts of data. If you
mean a program image, there are tools that do such things. I got an impression
that you haven't read the TinyOS tutorials and documentation before starting,
so I suggest you start from there.
Regards,
Harri

Dear all:
I want to transmit image via my sensor node

and then tranmit it via the wsn network to another node.
but now I don't know how to read message from a pc.
