How can I tell if somebody's using fake pictures?

[eddie]

Well, I use a website called Quotev if any of you know what it is. A lot of the people on there just go to google and use those pics and fake other people. Are there any programs or websites where I can upas a picture and it tell me who it is or anything? Thanks guys

You can reverse image search an image on Google but that doesn't guarantee whether it's fake or not. But it will show if it's been used on other sites.

there is no 100% way to be sure... you can use tineye.com tho and make your best judgement

Some images on a web site you can left click on that image and bring up the properties of it and some you actually have to save the image to the computer and do the same thing, however it does not mean you will find the information you seek.
