Does exist a way to see the X and Y coordinates of the left top corner of the current marquee selection in photoshop CS2?
In the info tab, it seems that the application shows me only current x and y of the cursor, and the width and height of the current selection and nothing else.
Working with sprites it would be good to have a function like that...
Not that I'm aware of. If what you're selecting extends all the way to the right and bottom of the image, you could use SHIFT + CTRL + i to invert the selection, thereby giving you the origin of your marquee selection. If you're working with sprites however, I recommend taking a look at Sprite Cow.
