Unsolved issues in using QML List View

How to increase the speed of loading of images in a listview in qml ........? And while scrolling, flickering of images also happen and in the first scroll images are moving very slowly.....,how to resolve this issue.......?
Images are read from the file using some id (key) in the CSV file.This CSV file has got many attributes related to it and all these are fetched.
As unable to upload file.Below is the code listing.With Thanks```
