.Gifs my friend
download and install gimp
www.gimp.org
open your first pic, then go file open as layer and pic the next one and then the next and so on.
file, save as.
enter the file name then delete the .xcf extension and put .gif
should say that .gifs cannot handle layers, export as animation? click yes and pic your timing per frame

if you have photoshop, you can use imageready instead
