Well this is how I'd do it... but I'd love to know if thre's a better way...:
CTRL A (to Select All)
CTRL ' (to bring up a grid to align to)
EDIT / TRANSFORM / PERSPECTIVE... (or distort, rotate etc. as needed)
Tug the handles around to line everything up how you want it then apply.
Crop the image to bring the edges square again.
HTH![]()
Control A= Select all
Control T= Free Transform
Grab the handles at the corner of the image , hold down the control key ( this allows you to move only handle you've grabbed.) and move that part of the image.
