[renamerOnUpdate] Add support for renaming images

[echo6ix]

Feature request to add support for image handling in the same way scenes are handled.

Element fields

There don't seem to be any unique fields for images that don't exist for scenes. However, there are elements unique to scenes that do not exist for images. These unique fields should just output a null value if the user incorporates them into an image template.

Galleries

A dedicated template for galleries, that is, the zip file. I'm not asking for the renaming of the images within zip files, just the renaming of the zip container itself, if possible.

I would really like to see that. That would make image and gallery images handling easier.

Should also include Foldernames (= galleries) which contains the images. Renaming the gallery title should rename the folder name.

A push from me to also support images :-)
