I have a problem with images. I only want to reload 1 image when I click on the context menu.

It seems you're going to be using
chrome.contextMenus.update(integer or string id, object updateProperties, function callback) as mentioned in the Google contextMenus guide. It updates a previously created context menu item. Looking at the parameters that it accepts on onClick, it seems to accept, images, videos, and audio.
