The first image is probably coming from your theme, you can remove the other image by editing the recipe and removing the [cooked-image] shortcode from the recipe template:

Hi,
I have the same problem. Feature image is display twice.
First before the recipe and second where the [cooked-image] tag is.
I want to keep the [cooked-image] so how to remove the first image display ?
@dj_caribou: The first image is coming from the theme, you will need to do one of the following:
- Disable featured images via the theme options (if available).
- Ask the theme developer how to disable features images on the “cp_recipe” custom post type
- Hide it with some Custom CSS via the Customizer
I can help with the custom css option but I would need to see an example page where this is happening (URL). Thanks!
