Neither the GIF data adapter nor the ImageJ data adapter (a more
general-purpose image adapter that uses ImageJ's functionality)
support animated GIFs.  It is certainly something that I think
VisAD should support eventually, but I don't have time to look
into adding it right now.  It would fit naturally with VisAD's
"FormBlockReader" logic for reading in individual data blocks
(in this case, images) from a file on disk.

However, you should at least be able to import the first frame
of the GIF into VisAD, as Tom says.

Tom, I'm curious as to how you got the rest of the GIF data
into the program.  Did you split it into multiple files with
some image software, or did you have code for reading all
frames of an animated GIF?
