In case if you use sorl-thumbnails , widget is like this:

from django.contrib.admin.widgets import AdminFileWidget
from django.utils.safestring import mark_safe
from sorl import thumbnail


class AdminImageWidget(AdminFileWidget):
    def render(self, name, value, attrs=None):
        output = []
        if value and getattr(value, "url", None):
            t = thumbnail.get_thumbnail(value,'100x100')
            output.append(''.format(t.url))
        output.append(super(AdminFileWidget, self).render(name, value, attrs))
        return mark_safe(u''.join(output))


class GalleryImageForm(forms.ModelForm):
    """
    Image Admin Form
    """
    class Meta:
        model = Image
        widgets = {
            'image' : AdminImageWidget,
        }

class GalleryImageInline(admin.TabularInline):
    ...
    form = GalleryImageForm
    ...
