This is to assist image generation models such as Auto1111, or Fooocus and its derivatives apply random keywords within an prompt. It should be saved as a .txt file in the wildcards directory. (Note that Ruined Fooocus uses a different location.)
Usage: Simply put two underscores around the filename prefix. i.e. __womensHairStyles__ in the prompt. For example "Close up shot of a beautiful 18 year old woman with her hair in (((__womensHairStyles__))) style,"
This will then cause one of the items in the list to be inserted into the prompt. For example "Close up shot of a beautiful 18 year old woman with her hair in (((__flip hairstyle__))) style", next prompt in the batch could be "Close up shot of a beautiful 18 year old woman with her hair in (((__360 waves__))) style".
Keep in mind that the checkpoint or lora may not recognize the style and will produce a 'default' response.
