I personally prefer the older Google Images. For one, I lose the ability to scroll the website immediately after finding it. I do this, for example, when I'm searching for some algorithm by first finding a diagram that I think is clearer and then going directly to read the explanation, or when searching for a recipe by looking for the image first.
I find the new interface to be slightly cluttered to use (with all the animations and uncomfortable feeling when scrolling), At some point, Yahoo (and others) had pretty cluttered interfaces and people eventually shifted to Google, commonly citing simplicity. For this reason, I find that taking the leap to 'everyone complains about changes' to trivialize the fact that many people may, in fact, appreciate simple interfaces.
There sometimes is a superior interface, and discussing the pros and cons of a new interface is very valuable.
