actually Tineye has add-ons for IE, Firefox, Chrome that make it REAL EASY to check on a photo.
go to
http://www.tineye.com
click on "Goodies" at the top
get one of the add-ons for your browser
or scroll to the bottom to "Get the bookmarklet for any browser" [a bookmark that's very handy].
after you get the add-on or bookmark, when you're on a webpage w/ photos/images [dont have to be women :^], perform the action to do a tineye websearch of the image.
i like the bookmark cos it goes to tineye.com, downloads all images on the page and lets you search on each image. the add-on only allows you to search for a specific image.
