One of my website usually resize images on the fly based on user screen resolution. I am thinking about at one tweak. I wish to cache those particular resized images using litespeed. Is that possible to cache only images. My http header response for a resized files looks as follows.
Code:
HTTP/1.1 200 OK =>

Content-Type => binary/data
Content-Length => 261741

In the above user has requested for 1728x1080 resolution, and image resized from original to requested resolution on the fly without storing that resized file. I want to cache those resized images to be able to serve for another user using Litespeed cache.

Is it possible? Nevermind about file size and storage.

LiteSpeed cache doesn't cache static files, like image files etc. for your case, you might need to keep a few selected common resized images to make it retrieving faster next time. Everytime resizing the image on the fly will definitely slow down your site performance.
