You can define an imagetemplate in the movie tag:
http://www.unidata.ucar.edu/software/idv/docs/userguide/isl/ImagesAndMovies.html
but that is used for all images. But you want to give each individual image a 
different
name. Right now you the isl does not support that. 

However, you could write out the
images using some template so you know the image names (e.g., image0.png, 
image1.png, etc.)
Then, if the ISL had a file rename command you could just rename. But it 
doesn't (we'll
add it to the todo list.) So you could write some jython that renames the files:
http://www.unidata.ucar.edu/software/idv/docs/userguide/isl/BasicTags.html#jython
Or write a shell script and exec it:
