WordPress Native Gallery makes to much spacing

hi
very nice site.

In your HTML file find this code

<br style="clear: both;">

and Delete that code.There are in total 4 lines of such code in all. So Delete all the 4 lines of code.

You will find the above code under this code

<div id="gallery-1" class="gallery galleryid-16614 gallery-columns-4 gallery-size-thumbnail">

As you have included a total of 13 images, I suggest you to use only 12 images so that your gallery will look awesome.

to remove the last image Delete This line of code

<dl class="gallery-item">

open this directory:

WordPress\wp-content\theme\twentyeleven-child or twentytwelve-child or whichever theme you are using

there you will find index.php file.

Open that file and Do all the above procedure as i said
