[IDV #AZM-687357]: Images for the WWW

> Works just great Jeff, however I have one problem with the naming

> I`ll be using the images on the www, but the problem is the image
> names will be changing with each update/run (0z,6z etc).
> 
> At the moment they are named like: image_10_2007_02_20_12_00_00Z.png
> 
> That`s the 10th image taken from the 00z GFS. Then next run would be
> the 06z and it will likely be named: image_10_2007_02_20_18_00_06Z.png
> or something like that. This would mean having these images online on
> a website would cause issues, the images would break every six hours
> because the name changed.

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:
