Posts table image options

Image size

The image_size option controls the size of the featured image if you have included the image column in your table.

The default image size is 70x70 pixels. You can use a width × height value in pixels or any standard WordPress image size such as thumbnailmediumlarge, etc.

If you specify only one number, this is used for both the width and height. You can include px after the number or omit it. So image_size="70px" is the same as image_size="70".

You can set the image size option globally in the settings page, or add it directly to the shortcode for individual tables.

For a square image 50 by 50 pixels:
[posts_table columns="image,title,content" image_size="50"]

For an image 40 pixels wide by 60 pixels high:
[posts_table columns="image,title,content" image_size="40x60"]

To use the medium image size:
[posts_table columns="image,title,content" image_size="medium"]

My images are displaying in the wrong size

Image sizing is very complex in WordPress, and can have unexpected results. A few tips:

  • Your images must be the correct proportion for your chosen image size. For example, if your images are square and you set image_size="50x40" then the images will still appear square.
  • If you're using the built-in image sizes (e.g. thumbnail, medium or large) then you can check their sizes in Settings → Media.
  • The column widths may be overriding your image sizes. For example, if you have set a fixed width for the image column and a specific image size then these options may conflict.
  • If you're really struggling to get your images the correct size in the table then you can resize the original image to the correct size.

The table is loading bigger images than it needs to

If you set a custom image size, WordPress will look for a registered image size that either matches this exactly or shares the same aspect ratio.

For example, let's say you set the image size to 50x100, and your site has a registered image size of 100x200 but none that matches exactly. In this case, the aspect ratio is correct so the 100x200 image will be loaded behind the scenes, and displayed at 50x100 in the table.

If there is no registered image size with the same aspect ratio then the image will be displayed as the correct size in the front end, but the full size image will be loaded in the background. This could slow down your tables.

You can use any of the following methods to prevent this from happening:

  • Instead of setting a custom image size, use one of the registered image sizes which are listed under Settings → Media (e.g. thumbnail or medium).
  • Go to Settings → Media and edit one of your existing image sizes to match the aspect ratio of the images in the table, and then regenerate your thumbnails to update all the existing images. (Warning: This will also change any images that use this size elsewhere on your site.)
  • Register an additional image size which matches the image sizes that you want to display in the table. Again, you will then need to regenerate your thumbnails to create a version of all your existing existing images in the new size.

Image lightbox

If you use the image column in Posts Table Pro, the image will open in a lightbox when someone clicks on the image.

The lightbox uses the Photoswipe library and is enabled by default. If you would like to disable the lightbox feature, you can untick this option on the plugin settings page:

You can also enable or disable it for individual tables by setting the lightbox option in the shortcode:

[posts_table lightbox="false"]

Can I change or restyle the image lightbox?

The lightbox uses the Photoswipe library. Unfortunately there are no options to customize this, but you can achieve this by adding additional CSS to your site.

Linking to the post page from the image column

If you would like the image to be clickable and take the user to the single post page, you need to disable the lightbox as described above. Once you've done this, the image column will instead link to the relevant single post page - see the links article for more details.

How to remove images from the table

If you don't want to include images in the table at all, then you can delete the image column from the list of table columns. Please see the article about editing columns in the table.
