How to optimize image loading from cache when scrolling ListView?

There is a listview with pictures that are pulled over the network using UIL. Pictures 100-300kb each.
The problem is the delay in scrolling when they are pulled from the UIL cache. She's too big.
How is this problem solved in large applications?
For example, applications for Facebook or VK: to see a placeholder instead of an image, you need to scroll very quickly.
