trancparency and flag waving

how do i animate these.
simple instructions please!

“I” to insert keyframe
I’m pretty sure there’s a flag tutorial on, but the blender server seems to be down at the moment.

thanks spacetug.
that solves the transparency.
can blender accept images - gifs - that are partly transparent?

i couldn’t find a tutorial on flag waving- i thing there is a tool for it.

thanks richard
i shoulda looked in youtube!

does blender accept clear parts of pictures?

says it is 2.5! but doesn’t say how!

i have a backgrounfd picture and a picture in front of it (one of several.)
when i alpha the picture it makes a hole in the background!
am i doin’ something wrong?
