Attachment_fu - Problem in displaying image from DB

Hi,

I am using attachment_fu plugin to upload images to database(I am using
":storage => :db_file").

Now I want to read the image and display it in a web page.

I am able to read it correctly, but i don't know how to display this
read image in a webpage. Both send_data and send_file are for
downloading the image.

I tried with "image_tag" method but didn't succeed.

Any suggestions are appreciated.

Thanks in advance...
