Premium version:
The plugin uses two main modes of operation "Processing image paths" and "Working with html image tags". In the basic version, you can only choose one of these modes. Image Path Processing mode - we process all images, but a limited part of the plugin functions is available. In the "Work with html image tags" mode, only images from the "img" tags are processed, but all plugin functions are available.
In the premium version, you can use both modes at the same time.
