I just reported about a Google Image update but it seems with that update, Google has removed a very important feature. Typically, if you click on an image in Google images, it will open that image in a framed window. Part of that framed window will contain a Google Search box at the top and the page the image came from in the bottom half.
What is now missing is the "Remove This Frame" link from Google Image search.
You can of course click on the "Below is the image in its original context on the page: URL here" option to take you directly to the image source. But the "remove this frame" link has been removed.
A WebmasterWorld is discussing this now and some are mentioning that Google is currently testing out new layout options for this feature. For me, I currently don't see the "remove this frame" text anywhere. However, some say it was "renamed and moved to the other side of the screen." Time will tell.
