The Web contains a vast pool of free graphic images. Many of them exist inside PowerPoint slideshows. By extracting images from PowerPoint presentations, you can build a library of free, quality pictures and photos. Even if the images are good, you may be able to make them better by editing them. Using a simple file renaming trick, you can import PowerPoint slideshow images into Photoshop and tweak them any way you like.
Extract PowerPoint Images
Open Windows Explorer, and navigate to a folder that contains one of your PowerPoint presentations.

Double-click the folder to display its contents. Find a PowerPoint file whose slides contain images. It will have a file extension such as ".pptx," ".ppt" or "ppx."
Click the file to select it, and press "Ctrl" + "C" to copy it. Press "Ctrl" and "V." Windows Explorer pastes a copy of the file into the window. The word "Copy" will appear in the filename.
Right-click the new file. A drop-down menu appears. Click "Rename." An input box appears around the file name. Highlight the file's extension.
Type over that extension to change it to ".zip." For instance, if the original file name is "MySlideShow.pptx," change the name to "MySlideShow.zip." Windows Explorer converts the file into a ZIP file that contains folders.
Double-click that ZIP file. It opens to reveal a list of folders. Double-click the folder named "ppt." It opens and displays its folders.
Right-click the "Media" folder, hold down your left mouse button and drag it to your desktop.
Release the mouse button. A drop-down menu appears. Click "Move Here." Windows moves it to the desktop. This folder contains the presentation's images.
Import into Photoshop
Launch Photoshop and click "File."
Click "Open" to display Photoshop's "Open" window. This window displays your computer's files and folders.
Click the "Desktop" icon to display your desktop folders.
Double-click the "Media" folder to open it and view its image files.
Double-click one of the images to open it in Photoshop.
