Disc image size question

When offering a disc to customers, what size (hi-rez) Jpeg is on there?
To clarify; if I crop & size 300ppi for 8x10, a 8x12 or 5x7 will not crop correctly due to the different ratios.

How do you get around cropping issues?

I do not crop the images. High res is exactly what comes out of the camera. If they want cropping I would have to know what size prints they are going to make. If you crop them to 8x10 and they try to print 4x6 your in trouble.

Want them cropped? Order from me.

I can just see an argument coming. As they stand in Wal Mart/CVS/Walgreens and unsuccessfully try to have photos made, it will no doubt be my fault.

More and more people want the files for this purpose though. I just took the stand that if I have to crop and process for each standard size I am sure as heck going to charge for it. Their goal is to beat me out of print sales. (sports) Okay, but I am going to gain something for my efforts.

Appreciate your reply.

If you decide to crop every standard size you will one day get the question "Why does my 4x6 show so much more then my 8x10?"
if you provide them with files you should also educate them on how to use them.
