question about plugin

I like the plugin.

After I rename the image file, at the top of the image listing
in the “File name:” setting ) ( at the top, to the right of the image itself ) – It stills show the original file name. It hasn’t changed.

Confused.

At the bottom where your “New file name:” entry is –
where it says “current filename is:” this is correct. But
the top entry is not.

Please Advise.
