You may (or may not) have noticed that in WordPress if you want to insert an image gallery into your post it does not give you the option of insert a gallery only 1 column wide.
This seems like an oversight. I have seen loads of photo and inspiration blogs around that often include multiple images in a single column so it would seem that being able to easily insert a single column gallery would be a useful feature.
Fortunately it is possible to insert a gallery one column wide, just not through the popup media window. Here’s how…
How to insert a single column gallery
It’s just a simple shortcode:
Unfortunately in the Visual editor, when you go back to edit your post the gallery shortcode will be displayed as a gallery preview. If you click the gallery edit button (top left) then the media window will pop up but the columns menu will default to 3 as there is no value of 1.
So, what’s the fix?
It’s a change to WordPress core code but it’s really simple. Just edit wp-admin/includes/media.php and around line 1818 insert an select menu option with a value of 1.
1817 1818 1819 1820 1821
<select id="columns" name="columns"> <option value="1">1</option> <option value="2">2</option> <option selected="selected" value="3">3</option> <option value="4">4</option>
