I have a digital picture that 180dpi - my publisher requires at least 300dpi
- how do I increase the dpi?

You retake the picture with a better quality camera, or resize the picture
down to a smaller size.
Or you could wave a magic wand, if you could find an "increase quality"
incantation. You might look for one that would magically correct all the
grammar in all my documents while you're at it.

Can you find one that fixes typing errors too?

And a Norwegian-English perfect translator?
Actually you do not increase dpi in i picture.
You can increase/decrease dpi on a printout, but on a electonic image I
would rather use ppi (points per inch).
An that one is also not a subject for increasing/decreasing, is it?
A picture contains a number of pixels, horisontally and vertically (as you
all know).
You can change the number of pixels, and thereby the amount or detail of
information in a picture.
Then you decide how many ppi you are going to put to each inch (or cm) in a
picture by adjusting the size of the picture.
Or you decide the size of the picture and thereby adjust the ppi.
Anybody got the idea?
Sorry, its early friday in Norway, and I am looking forward to the weekend.
Just had to get it out.

Bless you!!! One of my pet peeves is people who want to increase the dpi of
their monitors. ARGH!

What you can't do, though, is change a 3"x2" 150dpi picture to a 3"x2"
300dpi picture.
Doing the resample operation would not increase the amount of detail, it
would just add more of the same and increase the filesize unnecessarily.
A pixel can be referred to as a dot

Well, now that you mention it--
Analog RGB Monitors have a variable pixel density and a fixed dot per inch
(hardware). It's possible for one pixel to span more than one dot. LCD and
digital monitors also have a fixed number of dots per inch and can be set to
resolutons that cause more than one dot to be illuminated for a pixel.
(Oversimplification) So a given picture size in pixels can be reproduced in
various dpi formats. Having said that-- The publisher should be specifying
the picture size in pixels instead of dots per inch, where the picture size
in pixels has a certain hight width format as well as a size. The other
problem is that a digital camera has a fairly small sensor, so the resulting
picture from such a camera actually has a very high pixel per inch count.
The image from the digital camera, by convention, is usually set to report a
resoluton of 72, which matches most default monitors. In other words, it
would be more useful for the publisher to say that the photos must be equal
or better than in resoluton to those produced by a 3.1 Meg digital camera.
