I've found I add !gi to my search string subconsciously nowadays, when I know I want to perform an image search, whereas before I would enter my search terms, wait until google had loaded its results and then hunt for the images link to get the full image search results.

In some way it's 'trained' me to perform more targeted searches from the outset.

The slight lag before getting results is noticeable though.

I'm going to stick with the upstart for the moment nevertheless.
