When you paste an image directly from Adobe Photoshop onto your PowerPoint slide, you’re pasting not only the image itself, but also a bunch of application overhead that lets you double-click the image on the slide to open up a Photoshop window and edit the photo from within PowerPoint. OLE stands for Object Linking and Embedding, which is kind of a dumb name because you can’t link and embed at the same time. It’s much better to save the image to your hard drive and then use Insert → Picture → From File to insert your images onto your slides. THE FIX: When you paste or drag and drop an image onto a PowerPoint slide, it sometimes creates what is known as an embedded OLE object. THE ANNOYANCE: I dragged and dropped a picture into my PowerPoint file, and now my file is humongous.
