I stand corrected: apparently gnuplot can create gif animations

For one thing it is using version 4.2 of gnuplot

Yes. But if you need that feature, then you have a good reason to
upgrade to 4.2

And that demo animates outputs from an equation.

Huh? You must be looking at the wrong demo.
The demo plots a world map from a data file, changing the view
incrementally between frames of the animation.
Try this link:

http://gnuplot.sourceforge.net/demo_4.2/animate2.html

I have data generated from a programme and I have both the data and gif
plots at successive times of interest. I want to animate these gif
files.

The animation procedure in gnuplot does not care what kind of
plot you are making. Functions, data, images, ... all OK.
In a nutshell, the command sequence is

set term gif animate
set output 'my_animation.gif'
plot <frame 1>
plot <frame 2>
...
plot <frame N>
unset output

Hi, I'm able to do it in the GIMP software. But I still wanna do it in
gnuplot.
I'm getting the following error, ethan:

set term gif animate
Terminal type set to 'gif'
invalid color spec, must be xRRGGBB

Another thing by 'frame 1', 'frame 2', ... 'frame N' do you mean the
the data file or the gif file?

thanks
