You could remove your camera's SD card, put it into a card reader, and access your picture files that way. But why not save yourself the trouble and get a camera cable? By using a camera cable, you can plug your camera directly into your computer and copy your files to your computer to be edited in Photoshop. Your computer probably came with a camera cable when you bought it, but this is often the first thing people lose. It's unfortunate, because they always need it later. Luckily, you can buy a new one at your favorite wholesale merchant.
