Stroke, Layer Style - Avoid Rounded Corners

[Stu]

Hi, I'm trying to create a cover photo for my photography page made up of individual images. I realised after I had them arranged that I should have put a border on them beforehand and have been trying to do this afterwords using the Stroke Layer Style. This seems to work fine except when I choose 'Outside' (which I want) the frame has rounded corners. If I choose 'Inside' the corners are square. Any way to make the corners square with outside or do I need to start again? I'd usually add a frame by extending the canvas on the original image.

This irritates me so much.  No, I'm not aware of a way, sorry.  If you find one, can you let me know?

Only way I can find is to create shape layers below the image layers which is a bit painful!

Yeah, you're not kidding.
