    You don't need a photoshop master, you need a maths/stats master. Google a paper called Image Forgery Detection by Hanry Farid. It outlines all the basic techniques used in forensic image analysis.

    A quick and dirty one you can do is a Principal Component Analysis. Running an image through a PCA can very clearly show up where things have been photoshopped in some cases. There are many techniques required for a full analysis though.

    Not only that but if the thing in the screen shot is of a Web page then it's not even necessary to photoshop it to manipulate the values displayed in the image. You simply hit F12 and use the developer tools in the browser to edit the DOM directly and change what the Web page displays and then just screenshot that. Completely undetectable.

    Maybe would be easier to use tineye.com and google images, upload the image there and compare results...

    The only issue that a screenshot can be faked without using PS, a webpage can be modified with some quick javascript edit, so you will never be able to tell that it was altered or not, unless it is stupidly done lol
    So even if you can say with 100% certainty that it's not photoshopped, it still can be edited.

    Ask for video proof, that's harder to fake or get teamviewer access.

    We both touched on the same point of being able to fake the data by editing the web page rather than the image itself. You can even fake it on video or team viewer. For video it's a little easier than teak viewer but for team viewer it just needs to be more thorough. Essentially, clone enough of the site such that you can navigate to it, log in and display the page you are trying to "prove". THEN (and this is what makes it 100% believeable) host it locally on your machine, run your own DNS server locally that resolves the url of the website (say PayPal) to the local loop back IP address. The end result is you can open up your browser and type paypal into the address bar and have it load your locally hosted clone which says whatever the hell you want it to say.

    Unless you allow them to log in to the real account in an untampered with environment it can be faked in so many ways.
