@Geppetto Luis – when I started you had not replied... I kept on adding extra stuff to my version as I was bored!
EDIT: Original version 1.0 updated, there is still one "flaw" that I would like to overcome... Can anyone help to improve the script please with a check for no layer selected?

Save As Copy WebP via Google Plug-in with Active Layer Name.jsx

Script save webp with active layer name
ATTENTION: * Script will silently fail if there is no active layer (To do: add an alert to warn if no layers are selected, easier said than done...)
* Layer names will have all special characters removed in the save file (the original layer name will not be affected)
