How do i get to know if an image is rendered in a webpage? (django templates)

Question

I ahve this code, the trouble is few of the images are having names, but corresponding to the names the files are not present, how can i know if the images are being displayed, i mean some if statement of something like that.

<img src="{{ STATIC_URL }}images/{{web.image}}" />

The above code is used to render my django image in a template. Thanks.

Answer 1

finally i have found a solution using sorl thumbnail : http://thumbnail.sorl.net/examples.html#template-examples

{% thumbnail item.image my_size_string crop="left" as im %}
    <img src="{{ im.url }}">
{% empty %}
    <p>No image</p>
{% endthumbnail %}

it works for me.
