PreviewImageWidget

PreviewImageWidget is a fairly simple widget that you can use for previewing an ImageField. The image-box is located at left of the Browse button as you can see below. If you click the image-box you will notice that the image will be open in a modal-box with a bigger size.

image-box: preview of the image

modal-box: it pops up when you click on the image-box

Settings for PreviewImageWidget

Add DJANGO_MEDIA_TOOLS_CONFIG to your settings.py file if you want to set defaults for PreviewImageWidget.

DJANGO_MEDIA_TOOLS_CONFIG = {
    # max sizes of preview image-box
    'preview_max_height': '150px',
    'preview_max_width': '150px',

    # max size of preview modal-box (the box that is opened when clicked on image)
    'preview_modal_max_height': '90%',
    'preview_modal_max_width': '90%',

    # Hides 'currently' label on admin
    'hide_currently': False,

    # Shows the image url at the bottom of the modal if set to True
    'show_caption': True
}

How to use PreviewImageWidget

sample models.py

class Product(models.Model):
    name = models.CharField(_('name'), max_length=50)
    photo = models.ImageField(_('Photo'), upload_to='testing/product', blank=True)
    banner = models.ImageField(_('Banner'), upload_to='testing/product', blank=True)

sample forms.py

from media_tools.widgets import ImagePreviewWidget
from .models import Product

class ProductForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = '__all__'
        widgets = {
            'photo': ImagePreviewWidget(preview_max_height='80px', preview_modal_max_height='600px', hide_currently=True, ),
            'banner': ImagePreviewWidget(preview_max_width='150px', preview_modal_max_width='50%', show_caption=False),
        }

As you can see you can override the default settings by giving them as kwargs.
