Hi Luca,

> <img src="{% static "mysite/scorr/{{a}}" %}" width="100"
> height="100" </img>

Try {% static "mysite/scorr/"|add:a %}

Hi Luca,

Did {{ a }} solve the problem?

Cheers,

Raoul

Luca,

You can't nest a variable evaluation (via {{}}) inside a tag
execution {%%}.  But you can put them side by side to achieve
the effect you want:

'{% static "mysite/scorr" %}'/{{a}}'

There are probably 3 ways you can do this:

1) Use a Filter 

You should be able to use the "add" filter to concatenate two strings. 

2) Map the elements of your array in your view with the contents of settings.STATIC_URL. 

3) You can't nest a context variable inside another tag like you're trying to do but you can concatenate two variables together:

{% static 'my_app' %}/{{filename}}

I hope that helps.
