Your Questions About Google Images

admin answers:

Upload your image to a free image host, then submit the image url to Google. Make sure you name the file something relevant, because that’s how people will find your picture from their search.

You can’t upload a file to Google Images directly.

You can upload your photo/image to one of the following:

http://tinypic.com/

http://photobucket.com/

And then submit it to Google:

http://google.com/addurl

if not you can install them from
.http://filehippo.com there are other sites ~cnet~major geek for example
if this is not the answer
have you got your pop up blocker on ~this can also cause this problem
it may be a problem with a temp file or a web cookie
try http://ccleaner.com
install and run it (then at least weekly)
it will clear all temp files and browser cookies left behind every time you browse the web (normal occurrence on all PC’s ~laptops)
if it does not solve the problem it will do no harm and will improve your PC performance and give you memory back.

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.
