First of all, do not use the category "Bugs" for specific problems with one extension. Always use the corresponding category, here "LLFJ - Lazy Load for Joomla!".
You can not exclude modules or plugins from being processed. If you have a problem with images, then exclude these images by entering their names into the corresponding field in the settings of the plugin. You can also exclude components or URLs!
By the way, this is not a bug. Some libraries are loading images dynamically and this can lead to conflicts with the lazy loading functionality. This is exactly the reason why I've included the exclusion options!
You have to enter the name how the component is named internally, so for the content component you have to enter "com_content". Just check how the component is named (you see it in the component folder or in the address bar if you enter the component in the backend) properly and enter this name in the settings of the plugin.
