WPSSO v2.9 Adds New WordPress Settings Pages


WPSSO version 2.9 has been released and adds two new settings pages under the WordPress Settings menu item, along with a number of smaller changes to improve the settings tab layout, and improve non-debug performance.

The new “Image Dimensions” settings page includes sizes for every WPSSO specific image dimensions, including Facebook / Open Graph, Pinterest, and all Twitter Cards. Additional text has also been included to suggest better image dimensions settings than the default values (which have been selected to match the WordPress defaults).

WordPress Lies About Image Sizes / Dimensions


There are a few functions available to retrieve the URL and size of an image in the WordPress Media Library, but few people know that these functions will often lie about an image’s dimensions.

As an example, let’s define a custom image size of 1000 x 1000 cropped, and use image_downsize() to retrieve the URL and size of an image ID (this example can be used with wp_get_attachment_image_src() as well). I’ll use list() in the example, instead of an array variable for the return values, to keep the code more readable. ;-)

WordPress will return a URL for the image and the values of $width / $height may be 1000 / 1000 – it all depends on several factors.

Encode Small Images in Stylesheets

Continuing the earlier theme of Optimizing Images to Save Bandwidth and Speed Page Load, you can also encode small (background) images directly in your stylesheets. For each image / page element encoded within a stylesheet, it means one less HTTP connection for content, which in turn means pages finish loading faster. These images should generally be small and downloadable quickly — what you want to save is the HTTP connection overhead, not the download time (both images and stylesheets are generally cached after downloading). The images should also be encoded within sourced stylesheet files, so the stylesheet files can be cached by the browser. If you encode images within your content (using <style></style> tags for example), the encoded image will have to be downloaded for every page view, so although you’re saving HTTP connections, your page size has increased. By encoding images in sourced stylesheet files instead, the browser (and content delivery services) can cache the whole stylesheet, including the encoded image(s).

Optimize Images to Save Bandwidth and Speed Page Load

A few weeks ago I mentioned the wesley.pl script from GitHub to optimize images, and how I had modified it to keep (or discard) the EXIF / XMP information. Making sure images are as small as possible is important to save bandwidth and improve page load times (and google rank), so I think it’s worth discussing my image optimization process in more detail.
