It appears to me that you have a little arrow background image repeating in the verticle dimension (y) as the background of the block content area.
If what you really want is to associate the image with elements in the block content area (like the menu items or the text inputs in the search and login block, then you should edit the templates of those blocks to have those arrows as a background for a div wrapping that content element.
<div class="arrowback"> ## content ##
then define the class in a style.
Then you will need to position the image within the element, so you may need several class selectors to do the job completely.
Perhaps. Just a thought.
