To use recommended images in all graph paper press topics, simply select the recommended image from the link on the right side of the post editor screen. It’s good if the default recommended image size set in the theme suits your purpose. Otherwise, you can change the size by editing a little code. What is the reason for changing the recommended image size? In addition to making the thumbnail gallery larger or smaller, you can also change the aspect ratio of the size. For example, suppose you are a landscape photographer and your product portfolio consists of panoramic photos. In this case, if the default recommended image for the theme is a square, most of the images will be cropped. You can manually adjust the size to a more appropriate size to solve this problem.

This feature is useful if you want to display recommended images in multiple ways. For example, you can set the thumbnail size of the image library and set the size of the post title to be larger. The uploaded image must be at least larger than the size set for the recommended image. Uploading smaller images will increase the size and eventually make the image pixelated and blurred.
Rebuild the recommended image. Changing the size of the recommended image only affects the upload after the code change. All previous uploads are saved in their original size and must be recreated. If there are few images that need to be resized, you can upload them again manually. If there are multiple plug-ins, it is best to use plug-ins such as generate thumbnail to perform all heavy tasks. The plug-in is accessed through the tools menu

The problem with editing PHP files directly is that if a new version of the theme needs to be released and upgraded, it will be lost. Record the added code and create a new function. Although you can insert PHP files, this can be boring, especially if you edit too much or often see new versions of the theme.
The subtopic solves this problem because the subtopic will remain unchanged when the parent theme is updated. functions. If you edit theme code in a PHP file, style sheet, or other file, it’s a good idea to always use subtopics.

Appreciate the resized new recommended image. Changing the size of the recommended image and adding a new image size is a very simple task, but it requires some code editing.
