When I take it in to be printed, the pics won't come up.

Put yourself in the shoes of others looking to help you.
Imagine if someone walked up to you and just said the things you've said. There's no way in the world you'd be able to give them meaningful help based on just what you've said. Keep in mind no one reading your requests has walked with you to see what you're doing.
Take the time to type up a complete description of what you're doing, what apps you're using, what systems you're using, what you mean by "won't come up", etc. You're not going to be able to get meaningful information through by treating the forum like an instant messaging system and just typing one liners.
If I understand the issue, what you are saying is that you have Opened Images in Photoshop, adjusted them, and finally Saved them to JPEG. Then, you send those resulting JPEG Images to a printing service, and the files do not Open for that service. Is that correct?
You state that the files do not Open at the printing service. What software are they using?
What are the specs. that the printing service have requested?
How do your specs. for the Saved JPEG's differ from those specs.?
Did the printing service get any error messages in their software, when attempting to Open those JPEG's? What were they, if they did?
Which printing service are you attempting to use?
