[Treehouse Presents - Quick Tips: How to Do a Reverse Image Search with Chris Zabriskie]

Hi, I'm Chris. And in this Treehouse Quick Tip, we're going to learn how to do a reverse image search.

I'm sure you've all used Google Images to find images before.

Let's look up my favorite band, The Monkees. Yeah, there's plenty of photographs there.

So Google Images is great for finding photographs, but what if you have a photograph and you don't know where it's from?

Let's look up a picture of a butterfly. So we have a bunch of pictures of butterflies here.

We want to use one for our site. This one looks nice. And we see it's from a blog—this blogspot here for Davao CIty.

I don't know how to pronounce that, but it looks like a nice place—got a butterfly house.

Are we sure we're actually able to use this picture on our site?

There's a few ways we can do this. Google Images lets us reverse image search.

So I've saved the picture over here on my desktop. I'm going to drag it and drop it just like that.

It's going to upload it to their servers, and it's going to look for it. Hey, that is a monarch butterfly.

Google Images is also a great way to identify butterflies.

So this tells me what it is, and it also gives me a bunch of pages that have this image on them.

But it's still kind of tough to tell where this actually came from. So let's head over to a site called tineye.com.

Here we can do sort of the same thing. Drag the butterfly over, it's going to give it a look, and it found all sorts of stuff for us.

The top one here is from Wikipedia. As you can see, it's been used on a lot of other blogs, as well.

But let's take a look at Wikipedia here, and we'll find this is actually part of a picture that's hosted at Wikimedia Commons.

And we can see here the photo's licensed under a Creative Commons Attribution-Share Alike license,

and some more details about the photo are up here.

Stand-alone version right here. Fantastic. Oh that's a nice, big one.

Let's do this one more time and search for The Monkees again.

Let's try and find this picture. Now it's at a website called 8notes.com. I'm not sure what that is.

But we're going to copy this, go back to TinEye, paste the URL here.

Let's see if we can use this picture of The Monkees. Well, best match, first result is Getty Images.

Now Getty Images is royalty free for the most part. Stock photography, repository—one of the largest in the world.

And it looks like this photo is not cool for us to use, unless we actually pay for it.

Let's see. Hey—$49, 3 month.

Forty-nine dollars for 3 months? Maybe this is something we want to license if we're writing a blog post about The Monkees.

But either way, this is not Creative Commons licensed.

So if you've got a photograph you want to use on your website or in your other project and you're not quite sure where it came from,

Google Images or TinEye are great resources for digging a little bit deeper into an image's history.

Now not every reverse image search is going to be quite that easy.

You may have to do some real research into trying to find something.

But never assume that just because you can't find where something originally came from, means that it's okay for you to use.

Chances are it's copyrighted, and you should treat any photo you find randomly online as something that is protected

and not able to be used in your project.

There are, of course, lots of places online to find Creative Commons and other freely licensed photos. Flickr is a great one.

If you go to Flickr and type in flickr.com/creativecommons—there it is—you'll find all sorts of images that are free for you to use

in your projects, as long as you're following the very simple licensing terms.

But no matter what photos or images you're using, be sure you have the proper permission or license to use it.

And when in doubt, a quick reverse image search should help you out.
