If you want to add a border to an image in Photoshop, there are a few different ways to go about it. The easiest way is to use the Border tool (B). To do this, first select the image you want to border and then click on the Border tool (B) in the toolbar. To create a simple border, just click on the edge of the image you want to border and Photoshop will automatically create a straight line border. If you want more control over your borders, you can use the options in the Border dialog box (Window > Borders). This dialog box has several options including width, color, and style. You can also add a gradient or texture using this dialog box. If you want to add a complex border, you can use one of Photoshop’s other tools such as the Rectangular Marquee Tool (M), Polygonal Lasso Tool (L), or Pathfinder Tool (P). With these tools, you can create custom borders that are specific to your needs. ..
