About WP Imsizer
From the official readme · v1.2.10Description
WP Imsizer (short for Image Resizer) is a plugin for WordPress which will save you and your clients or fellow blog contributors from having to manually resize all of your images to a more visitor friendly size. You can even restrict the total file size of uploaded images and even disable the WordPress image 2560px threshold limit which was introduced in version 5.3.
When someone uploads an image that is larger than your set dimensions, WP Imsizer will automatically scale it down to your desired pre-configured size and replace the original image.
Now can automatically set filtered image upload Alt, Title, Caption, and Descriptions from filename. Filters out hyphes, underscores, commas and extra spaces. Also, automatically capitalizes each word and will disable the default WordPress insertion of Titles from filenames.
The WP Imsizer Plugin is ideal for WordPress web sites and blogs that do not require super high resolution images. This will save space on your server, speed up your page speed performance, and reduce bandwidth utilization for both you and your visitors. As a result of being able to quickly display your media on your web site, this will most likely improve your search engine ranking.
