how to make image to cover entire module

can you explain me this question
i am new at joomla

when you install the module the first time, there are some example prefilled
Just publish your module with it and see how it reacts

the image in demo is not fullwidth

as you are on localhot I can not debug anything. You can try with the template protostar in position-1 to see how it renders, else you shall put your website on a live server temporary so that I can check

my website on server - www.galerijapeko.com
i want one image to cover the whole module like here demo.zootemplate.com/ (where it says - our menu)
please help
thanks

ok I see
the problem is that the module is encapsulated into a
<div class="container">
this is giving the width to the module and this comes from your template.
Unfortunately I can not change this, try to find in your template how to make this area fullwidth
