Creating a thumbnail for your blog is a great way to give your readers a quick visual representation of what they’ll be reading. To create a thumbnail, start by taking a picture of the front or back cover of your book or journal article. Make sure the photo is high resolution so you can make the best thumbnail possible. Once you have the photo, open Photoshop or another photo editing program and use the tools to resize it to fit on a 8×10 inch piece of paper.
Next, use the tools to add text and logos. When you’re finished, print out the thumbnail and put it in an obvious place on your blog page.
