Images optimization

Hello,

Do your gallery support some integrations with image optimization tools or services? Do you have some add-on for image optimization ?
Another question related with compression of the js and css. I’m using custom plugin for compression all js/css files but when it’s enabled on page with gallery, I can see only top gallery navigation without any thumbnail. On page where I publish gallery with shortcode in post on the front end I can see this shortcode, but now gallery which should be there. Please advise.

Thank you!
