Printing Cropped Pictures

Okay, I have a newb question regarding cropped pictures and photographic prints. Having just shot a bunch of photos, I then went ahead and cropped them without regard for size or aspect ratio. Some are cropped significantly (both horizontally & vertically).

Now I'm wondering what the heck do I do if I want to submit them to Costco for 4x6 or 5x7 prints? Is this something I should have considered before cropping them? What will the print shops do with cropped images?

You have replied to a 3 year old post with a rather odd answer.
Which photo editing software are you refering to that has this square bounding box?
Photoshop does not, it  will let you crop to any aspect ratio you wish.

Thank you Peter, that's useful information.

As far as working with originals, I've been working only with copies so no worries there.

I discovered this the hard way.

As least for CostCo (or anyone using a similar minilab) in photoshop Resize your image to as close as you can get it to your desired print size. Then extend the canvas to the full print size, this will add a blank white bar to one edge of the image. Save as a jpg with a new name at high quality. CostCo prefers the images submitted as 240dpi jpgs.

If you don't resize/extend the image it is automatically resized to fill the entire print area, cropping off anything that goes over the edge.

As a side note, you should never alter the original image file it is your digital negative. Always save any work with a new name, and leave the originals untouched.
