I had some photos of myself on another website, and have recently (about 2 weeks ago) made them private (they were originally public). You should only be able to access them if I give you the link and you have the correct password. However, Google still shows at least 25 images from said website, not only including the private images, but also including some deleted content as well. I tried to use the removal tool to speed up the process (because from what I gather, now that they've been changed/deleted, they should eventually drop out of Google anyway), but all my requests were denied because apparently the webmaster of the site hasn't blocked them. Whilst it's true I didn't go to the webmaster because it's impossible to find an email or postal address for them, given that they're now password protected, surely Google shouldn't have access to them anyway? Surely that'd be akin to Google displaying my emails from my email account? Other photos that I have since uploaded as private (that were never public) do not show on the image search. It seems a bit odd that, despite the fact I've got password protection on them, you can type into Google a specific term and they'll still show up and allow you to view them full size without the need for the password.

Is there any timescale for the results to drop out (presuming they will drop out in this case)? And why can't this process be sped up using the URL removal tool?
