In real life, people choose to border photos by putting them in a frame, with or without a mat. But there's no requirement to have a tangible border on a photo when the opportunities for adding one directly on the picture are almost endless. Add borders to images using the Adobe Photoshop program, where you're able to control the border colour, width and even how it appears on the picture. Create a cool border-on-border look for a photo going into a frame or use the digital border look for pictures for websites.
Open Photoshop. Click the "File" menu. Click "Open." Browse to the photo to add a border onto and double-click the file name.
Pull down the "View" menu and click "Fit on Screen" so you can see the entire picture. Skip this step if the picture already opened this way in Photoshop.
Pull down the "Select" menu. Click "All." A line of "marching ants" appears as a border around the picture.
Pull down the "Edit" menu and click "Stroke," which is Photoshop's word for border. The small "Stroke" window opens.
Type a number into the "Width" box. The larger this number, the thicker the border will be.
Click into the "Color" box to open the "Select stroke colour" window. Choose one of the colours for the border and click the "OK" button.
Check the "Opacity" text box. At 100% opacity, the border is completely opaque and will block anything underneath it. The lower the opacity, the more translucent it becomes and the more of the picture will show through from below. Type the desired number into the "Opacity" box and click the "OK" button. The border is added.
Click the "File" menu. Click "Save As." Type a new name for the image in case you want to access the borderless one in the future and click the "Save" button.
