Choose the image that you want to apply the mask to and make any cropping adjustments. I’ll be using this photo:

Add a layer mask.  The layer should reveal two thumbnails like below.

Choose the mask you will be working with.  Don’t worry if the mask isn’t the same size as the image we will adjust the size later.  Select>All and then Copy.  I’ll be using this mask.

Once back in the image you will be using, Alt Click (Windows) or Option Click (Mac) on the mask layer.  Your image should disappear to reveal a white background.  Now Paste the mask.  At this point, you can resize the mask image to the proper dimensions.

Once you have the mask sized properly, invert the mask layer by choosing Image > Adjustments > Invert.

To make sure that your image shows through the mask clearly, adjust the levels to make the mask pure black and pure white. Choose Image > Adjustments > Levels and pull in the right and left sliders like below.

The last step is to Alt Click (Windows) or Option Click (Mac) on the image layer to reveal your newly cropped image!
