Upload,Save and Retrieve Image from database by using their Id in Code First Method

from last 10 days I am trying many ways/example/tutorials which are provide in net to solve my problems. But, for all of those cases I fail down. I want to upload images for specific/multiple products, save them in database and display them in Home page by calling their ID. Can anyone give me step by step example/tutorials/link for this. Please don’t give an partial answer/suggestion. Because I am already bore about those.
