Google Errors

I've noticed a couple of Google bugs lately: one with robots.txt and another with Google Images.

The first Google bug is that Googlebot is not obeying a robots.txt file on one of my sites. The robots.txt file has been there since the launch of the site, but Google has cached the pages. The Google's Webmaster Tools robots.txt analysis confirm that my robots.txt file is correct, but Google is still indexing and caching those pages.

The second bug is that this site is getting traffic in Google Images for an image that is on another Web site and that doesn't appear on this Web site at all. I do not mention that image on my site and I'm not sure if I've ever seen the image, though the keywords are correct. The other site is from Finland and doesn't appear to link to me.
