Earlier while creating a instructional document I was inserting some images after I had edited them in Adobe Photoshop. Typically when I edit an image in Photoshop I generate the size of the image using pixels for height and width. I find this the easiest format to not only be universal but also to be the most accurate instead of using something like images. While lining the images up in this Word document I noticed Word uses Inches by default for image width and height. The below information describes how to modify the default measurement in Word for Mac from inches to pixels.
