Thanks for your question. MLA does not have any features for this task, but if you search the Repository for “image optimization” you will find plenty of good choices, e.g.:
Smush – Lazy Load Images, Optimize & Compress Images – WordPress plugin | WordPress.org
EWWW Image Optimizer – WordPress plugin | WordPress.org
I am marking this topic resolved, but if you have any problems or further questions regarding how MLA works with plugins like these, post an update and I will give you wat help I can. Thanks for your interest in MLA.
