Q. In google images, you can adjust the filter to display different levels offensive imagery (i.e. nudity, profanity, etc), but with the millions maybe billions of images online, how is it managed? Is there a google department in charge of surfing the internet to flag images? Or is it simply an algorithm of some sort?
If you're just going to guess, how about you just don't answer!

A. Google does have a user powered program that gets people to 'tag' random images for fun in their spare time. The more times an image is tagged with related keywords, the more confident Google can be that the image is what people are saying it is, and eventually those tags will be used to find that picture in the search results.
This is not the only way Google does it though. They do have computer algorithms that analyze and sort images very efficiently (it's the only way possible, even a team of hundreds of users could never tag every image out there).
Google Images also has an option to search for images with faces. I believe this uses the same algorithm used in Google Street View to identify and blur faces. Some people comment on the fact that it's pretty good at picking up faces even when they are not real, in one case the logo for KFC was blurred.
The algorithm for safe filtering is not perfect though... there are still things that can get through, especially if you use unusual search terms. I am studying Computer Science at University and in my opinion, the safe search option is done using a combination of algorithms and human intervention to help remove offending content that was not caught by the system automatically (as I noted earlier, this can only be done for a limited number of popular search terms though, so not everything gets filtered).
The algorithm most likely uses one of two methods (or both):
A) Identify the image as safe or not by determining whether the webpage it is hosted on is 'safe'. This is most likely done by analyzing words on the page in a similar way to how Google indexes pages in the text search. This can't be the only way since I know of websites that have completely unrelated text that don't have their images show up in the 'safe' search.
B) Attempt to identify pornography by either measuring the ratio of skin-tone colours to non skin-tones (i.e. try to determine how much 'skin' is showing) or using object recognition to identify 'offending' areas of the human body such as breasts or genitalia.
I should also mention that there is a report feature users can utilize to report offending images. This also helps filter out much of 'unsafe' images from popular search terms.

How do I download a bunch of google images quickly?
Q. How can I download all images from Google images? The original images that are linked from Google to other websites. Every time I try I end up at a site that seems to be malicious/full of popups.
Is there a way to download a bunch at once based on a search term or a program that does this for free?

A. Try Google Image Downloader.
Its free and lets you download up to 64 images at a time. You can add constraints like, Safe Filtering, Size, Color, Rights etc. too!
http://www.googleimagedownloader.com/
"Google Image Downloader (GiD) allows you to download images by entering a search term. It then hits the internet and downloads the full sized images from all of the sites Google images returns. So what does this mean to you?"
There are other programs that do this but I don't have any experience with them. GiD works well for me.

How can I reset google images to the classic view?
Q. why can't I view google images like it use to be, why does the image have to pop-up on top of the link page, and there is no direct link to the image, like it use to be. the image use to open in a different page with its own url, but now its on top of each other, and the urls are messed up. how can i reset it.
A. Here is a simple workaround for Firefox users (do this at your own risk):
Step 1) In the URL address bar, type about:config
Step 2) Search the setting named general.useragent.extra.firefox (its default value is Firefox/your current Firefox version in your case).
Step 3) Right-click > Modify.
Step 4) Clear its value and click OK.
And Google Images basic version is back permanently!
Try to search on how to do this on other browsers if you don't use Firefox as your default browser.
If you notice anything messy or issues on how the other sites are shown on Firefox after doing the steps above, you may revert back to the current version of Google Images by doing Step 3. But instead of Modify, choose Reset.
