Hi,
you do import the original django forms which does not now anything about templates etc. Please import from floppyforms as described in the example you have mentioned. So replace the line:

from django import forms

with:

import floppyforms as forms

Good luck! I'm keen to hear if that did work for you.

I tried that but,
It's not make any differance.

Can you please paste the relevant parts of the HTML output? I want to make sure that the image_thumbnail.html template is really rendered.
