Adjust an images resolution

How do you increase the resolution of an image?

I think we need more detail. What are you trying to do?

I uploaded an image to the web to get it printed and I was informed that it couldn't be printed because the resolution needed increased.

Printed by whome?
If you have the original and YOU want to print it. Just print it (Or do you mean a proper photograph?)
If you do use a program to raise the resolution, it will probably look worse.
HOWEVER ~
I myself have 'photoshop', which is regarded as the best in the world for picture editing. So if you want, I could make it any size you so desire and send it back to you via email?

Im assuming youve saved it to your desktop?
Whats the ACTUAL problem you have? Are you trying to send to an online 'service' to print a photgraph?

I saved the image to my desktop and then uploaded it to a website to get business cards printed. I am going of line now as I have an appointment this afternoon but I will check later.

It's likely to be a too low res image - meaning not enough pixels. And it sounds like you are confusing resolution with size/pixel count.

The "not enough resolution" message, is likely to mean, "the image doesn't have enough pixels to print at the quality/size required."

You can't up the resolution and resize, without making it blurry or jaggy, you cannot add detail that isn't there.

You can change the output resolution of a file say from 72dpi to 300dpi, but you'd have to retain the pixel count, e.g. 640 x 480.
If you resize the image, say from 640 x 480 to 2560 x 1920, i.e. increasing the size of the image, you'll just end up with a much larger image, but looking out of focus and blurry! Doing this in Photoshop or any other image program, will result in a poor quality image, regardless. You can still set the output resolution to 72, 150, 300dpi etc.

A printing service won't care of the output resolution set on a file (if you are talking photo printing), just the number of pixels available, as the output resolution is a trivial thing to set.
