Django-Admin custom ImageField

Question

I wanna add additional ImageField which obtains image from static folder to the model. I've tried to use some answers from the same questions, but there aren't anything about ImageField.

Answer 1

[SOLUTION]

I've found some way to load image via def

# admin.py

@admin.register(Course)
class CourseAdmin(..., admin.ModelAdmin):
...
readonly_fields = [..., 'headshot_certic_preview_image', ]
fieldsets = (
... ,
('Image info', {
            'fields': ('image', ('image_courses_and_course', 'image_dash'),
                       ('certic_preview_image', 'first_row_course_name', 'second_row_course_name',
                        'headshot_certic_preview_image'),
                       ),
        }),
...
     )
def headshot_certic_preview_image(self, obj):
        return mark_safe('<img src="{url}" width="{width}" height={height} />'.format(
            url=os.path.join('media/', obj.certic_preview_image.url),
            width=700,
            height=516
        ))
