I think it would be a lot better if it only displayed, say, 4-5 images max by default and of larger size. Since default google image search is slow, they need to return a ton of results. However here, since the user can refine results rapidly without their hands leaving the keyboard, I think you should only display 4, MAX 7 so they can scan all the results in a single isntant rather than performing multiple scans. Maybe have JavaScript to cycle next 5 images binded to arrow key without leaving keyboard. The human mind really only has visual memory for 5-7 objects at once, you should design it with this in mind if you want it to be truely instant. edit: another idea easier to implement. If the user types an exclamation mark as the next character, you instantly remove this from the query box. Treat it as a "Show Next 5" Indicator and load the next 5.
