On a display theme one of the 3 pictures URL points to wrong place.
$placeholder_image1 = get_bloginfo('template_url').'/files/household.jpg';
$placeholder_image2 = get_bloginfo('template_url').'/files/luotettava_kumppani_wide.png';
$placeholder_image3 = get_bloginfo('template_url').'/files/referenssit.jpg';
As you can see the code for all the pictures are the same, but on a website it shows as follows.
And the ones that work are as this.

Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
