Step 3 will now show you how to put two images side by side in Photoshop.
To put two images on one page in Photoshop, you’ll need to enlarge the canvas of one of the images. Let’s say you want to make the canvas of the first image larger.
To do so, go the first image tab and click on Image > Canvas Size in the top menu bar. This will bring up the Canvas Size dialog box.
If you want to put two images side by side in Photoshop horizontally, you’ll need to enlarge the width of the canvas.
As for my example, I know that both my images are 650 pixels in width. That means I’ll need to enter a value of 1300 pixels to get twice the canvas width that I have right now.
You can choose the measurement unit from the dropdown menu. There are a couple of options, including pixels, centimeters, millimeters, inches, and more.
In the Anchor section, move the point to where you want the first image to be on the canvas. For example, if you want the first image to be on the left-hand side, position the point in the center left field. Once you’re done, hit OK!
