Thanks for this, found it useful even 8 years after it was posted! Just in-case anyone uses this again, use:
from django.utils.safestring import SafeString
instead of
from django.utils.safestring import SafeUnicode

Thank you a lot! I cannot understand why there is no information about it

Having learnt a bit more since my previous comment, I believe the better way of doing this now is to use format_html(<html here>)

Just need to import:
from django.utils.html import format_html

Hope that helps 😊

In Django >= 2.0, you only need to wrap the return value of your field function with mark_safe:

from django.utils.safestring import mark_safe
class ModelAdmin...:
    def your_html_field(self, obj):
        return mark_safe('<image src="%s" />' % obj.image)

allow_tags no longer needed.
