Thanks for your question.
There are several ways to clip an image. Let me show you all three in the following video: https://cl.ly/2G0m2i0W1u21
First, I’m making a very rough selection of the object I want to cut out with the Pen tool (you can always finetune it later). Then, the first method is to drag the image to the path in the Layers Panel (the left panel). The second method is to select both element, make a right-click and pick “Mask with Shape”. The third way is to drag the image above the path in the Layers Panel and select “Clip” from the toolbar. Please note that I’m performing an “Undo” action between the methods so that I can show you all of them in a single video.
Please let me know if you have more questions.
