This idea came from a misunderstanding. What the ‘Custom performer image path’ actually does is set what the default performer image is (default silhouette.)
Since auto tag doesn’t check file names and make performers (at least that I’m aware of), what would be far more useful is, when the performer is created in stash the profile picture which is named after the performer is then placed in the content directory where the corresponding content file for that performer is. So the profile picture will sit next to the content folder in the alphabetically organized file explorer. helping large library owner see which performers they need to make. especially if a stashDB cant make or find the name.
