alot of people posted pictures from kinnernet 2005 at flickr.com.
the problem is, the pictures are displayed as Flash, which makes it
difficult to save. i don't know why would anyone want to prevent others
from saving his personal images, if he posts them on the web. however,
i found a workaround: disable JavaScript. this will cause flickr to
show the image in JPEG format.

mozilla: edit > preferences > advanced > scripts and plugins.
IE: internet options > security > custom > active scripting (disable).
