Overview
This WordPress plugin is designed for website owners who need to display images in black and white, such as in galleries where thumbnails appear in grayscale and become colorized upon hovering. The plugin eliminates the need to manually create grayscale versions of images by offering a streamlined function that integrates with your theme’s `functions.php` file. By using `grayscale_add_image_size`, users can easily specify custom image sizes with options for cropping and grayscale conversion. The plugin also automatically applies gamma correction to ensure high-quality black and white images, with the option to adjust gamma settings for more precise control. However, it is important to note that grayscale images cannot be generated if the original image size is smaller than the specified thumbnail size.
