Keystone correction

Is there any way to correct keystoning of images?

Using the Image ▸ Perspective Fix & Crop menu item should do the trick.

That maybe true, but there are now instructions on how to use this function

Use the corners and guides of the tool that shows up on to align to the edges of the object you’d like to straighten. Then click the “OK” button in the palette to commit it.

If you aren’t happy with those results, you can also try the Layer ▸ Rotate and Transform ▸ Perspective Transform menu item to fix the angles.

Fantastic, Thank you so much for the answer. Great work.
