A quick "how to" for animated GIFs:
To convert a set of still images into an animation:
Using the free GIMP software, load all the frames by using "Open as Layers", crop each frame to a fixed size (use the "Dockable Dialog", "Layers " to view and select each frame individually). Save (or Export) the stack of frames as an animated GIF, choosing the "animation" option.

I think all naturewatch projects should have at least one journal entry, so that there is somewhere for people to communicate about the project. So here it is :-)
