Problem solved.
Image is displaying just putting the image into the localhost
directories(/var/www/logo.png)
and giving the src attribute as
http://localhost/logo.png; `width="200" height="200"
alt="image is not available" align="right"/>

Use static files for that:

Re: image in browser

[Christian Jurk]

Why would you do that this way? The usual way would be to put your 
images into the static files and serve it from there. However, you 
should be able to do it that way using base64 encoding of the binary data:


from base64 import b64encode

def my_image(request):
image_data = open("/home/toor/Desktop/certificate/logo.png", 
"rb").read()
return render_to_response('myapp/bio.html', {'img': 
b64encode(image_data)},

context_instance=RequestContext(request))

After that, you can output your image inside the template by using

from the questions you have been asking on the list it seems to me that
you are unfamiliar with web programming. I suggest that you take some
time out to learn the basics of web programming and also to understand
how django works. I suggest you do the tutorial in the official
documentation. Also you should learn at least the basics of javascript.
The problem you have been bringing up in the last week is not best
solved by generating an image on the server side and passing it to the
template. The problem is solved by generating the data server side,
passing this data to the template and using a js library to generate and
render the image on the page.

Normally in an HTML file you put the image path in the src attribute, not 
the binary data (you can use a data URI with base64 encoding, but you 
almost certainly don't want to do that).

This is a strange thing to want to do. What are you doing with `img` in the
