You can use wp_get_attachment_image to retrieve the image URL for a respective size later on. The documentation for add_image_size is worth a read, particularly the last argument regarding how to crop and scale images. The original image size will also remain available. There is no limit to the number of image sizes you can define, so define all that you need. Newly uploaded images are then cropped to this size (plus some other default sizes) before being added to the media library. WordPress lets you define your own image sizes.

This post sets out the solutions I often use to tackle such image challenges for new WordPress website builds. Even a small barrier will stop a busy user from completing a task they don’t fully understand and regard as necessary. Even if they are somewhat aware, they might not have a convenient method to compress the images they want to upload. A lot of clients will not be aware of the ins and outs of image compression. The issue is really at the developer’s end. This is clearly not a good state of affairs for the end-user’s experience. Or, perhaps the image appears visually OK, but the file is outrageously over-sized resulting in minutes of waiting for the page to finish loading.

A Poor User ExperienceĮver gone to check in on your latest signed-off web project only to discover something is not quite right? The client has uploaded their own images and they are not only cropped incorrectly but the images are distorted in an attempt to ‘make then fit’. This is particularly useful if you are building a website that will be handed over to a client who will then maintain the content with no further involvement from you, the developer. This post introduces some considerations and techniques for handling images within WordPress.
