In addition to Google image searches, both Bing.com and Yandex.com do a pretty good job on reverse image searches. On Bing images, you need to make sure that "SafeSearch" setting is turned off. Both Bing and Yandex allow you to search by uploading an image from your hard drive or by using an image address from the web. Once you understand how to do a Google image search, it is not difficult to do the same on the other search sites.

First, thanks for the post, it is a good idea for people to learn to do deep searches. It was mentioned early but one major search engine that should be in your list is
https://www.bing.com/images/. When you have SAFE SEARCH turned off, it tends to provide better results than Google because Google is trying to cut down on porn searches (not much money in it for them I guess). And just like Google, you can upload a pic or you can put in a link from the web.
Another website that claims to specialize in reverse image searches is
https://deepmindy.com/ but I haven't ever got past "please wait". Interestingly, Deep Mindy is used on Imagefap on 1000s of pictures.
One method that has worked extremely well for me is to search for a picture on Google image search. On the results page it will say "Find other sizes of this image" if there are any (this it at the top near the image you are searching). Of course you can go through all the hits that show up but I take a quick look at the other sizes and see if any of them are on imagefap. If so, I follow that and see if the pic on imagefap has been searched by Deep Mindy. By this method, I have many times found full galleries of a chick that I thought existed in only a single pic on the web.

Another thing to remember with Yandex (if you really, really want more pics), is to "search similar images" even if there is no 'target' image showing in the little gaggle of examples. Randomly click on one and a big window displays miles and miles of images. The point of this is that, on rare occasions, a different image of the target model can be hiding a few scrollings down. I have experienced success doing this—admittedly there was an initial "similar image" at the top; but I was pleasantly surprised by two additional unrelated images of the same model hiding further down, out of sight. And these, of course, led to some more.
Also, on rare occasions, flipping (mirror-image) the image can turn up additional results. The search engines are supposed to do this automatically but I've kicked some goals doing it beforehand.
One final trick (once you know the model's screen name) is to just web-search her name. Add the word "milf" or "mom" or "nude"; or if she's young, perhaps "teen". You could also try the usual derogatory terms not tolerated with the threads in OCC.
