Random image for random word

Hy,
What i'm looking for is the following: visitors enters a word into a form and it is shown a picture. I am looking for something like:

<img src="http://samplesite/?word=dog">

Code (markup):

I dont know something like the first image from google search or similar.It would be nice if i could have used

<img src="http://images.google.com/images?q=dog">

Code (markup):

Is there any site on the web so that i can do something similar?

 

flickr has an API that can probably do it.

 

an api i can build it my own but i dont want to have to interigate another site every time. If i have 50K visitors/day i cant use the fsock to open a page and detect the image. I was looking for a that lind of link.Thanks.

You can cache the images so you don't need to request more than a few times per day.
