I would prefer that my images not be entered into the image search engines. I've banned Google's image bot, but I'm unable to do the same for Yahoo's or Ask.com's, because I don't know the names of their spiders.
A link to a listing of current bot names would be great.
stapel, bear with me, I am still learning about bots. What is the purpose of an images bot - and what do they latch on to? As I see it, the image has a file name only, which doesn't mean much. Do the bots link the file name to the alt text in the HTML file? And anyway, why deny bots access? If images are confidential, there does not seem much point having them on a web site (other than a secure one).
Not tyring to be argumentative, just trying to learn.
