Images lazy load ? plugin priority

Wordpress LScache Plugin: Images lazy load ? plugin priority

Hello, I use one of your functions to lazy load images. However i notice strange issue ? sometimes your plugin faill to replace placeholders with right images. This is probably connected somehow with plugin priority ? I notice that you plugin is working AFTER ads are loaded (with Ad Inserter plugin ? priority 999). Without ads everything seems to be fine. Is there any way to change priority of lazy load and load images before ads? unfortunately if something else did 999 , I dont think there is any way to make it load before that.
