Artist name change question.

When updating/changing an artists name via the ? beside the artist_tag, will the tag be updated for all of the artists images?

Also,

if you update an artists name via the "Artists" menu option will that update the artist_tag for all their images?

Re-written for clarity.

No, you have to retag the images with the new tag.

Or suggest an alias if appropriate, then I'll do it.
