If the h1 text is displaying correctly for all branches of this template, but some of the images are the same then the most likely problem is that the image files are the same image, but with different filenames.

I have model class with fields current_value and previous_value.
And then, in template used by listview, inside loop i have code like this:

{% if data.current_value < data.previous_value %}
    <img src="{% static 'app1/negative.png' %}" width="40" height="40">
    <h1>Price down</h1>
{% elif data.current_value > data.previous_value %}
    <img src="{% static 'app1/positive.png' %}" width="40" height="40">
    <h1>Price up</h1>
{% else %}
    <img src="{% static 'app1/neutral.png' %}" width="40" height="40">
    <h1>Price the same</h1>
{% endif %}

H1 text is displayed correctly, image is not. More specific – image for ‘else’ condition i believe is always ok, but for ‘if’ and ‘elif’ is displaying the same picture (one of them).

Confusing and infuriating. What am i doing wrong?
