The model field that relates System to Image is called
system_pictures, so you need to use that rather than the name of the
Image model. system_pictures gives you a Manager, so you need to call
all() on it (although you omit the brackets since you're in a
template). Finally, image_category will give you a model, not a
string, so you need to refer directly to the name field if you want to
compare it with a string.
So, putting that all together:
{% for pic in info.system_pictures.all %}
{% ifequal pic.image_category.name 'Header_Pic' %}
<img ... bla ... >
{% endifequal %}
{% endfor %}
