Hey Deva... Any chance you could pop up a rejected image? - Be interesting to see.

In short - Dpi is how much info is jammed into one inch of your image at a certain print size...

DPI is the resolution of the medium - a description of how many of the smallest 'bits' of an image can be represented in 1 inch (horizontal or vertical) on a monitor or paper. Digital Images 'themselves' are never 'XXX' DPI, they just exist as an array of pixels of a specified size (e.g. 1024x786 etc.). You should never need to ask the question 'I need a 300DPI image of....'

Some people insist on 300dpi for all printed media, while this is generally a good rule of thumb for highest quality glossy prints, you can often get away with a lower resolution, especially in newsprint where you were be hard pushed to see any difference between images at 100 or 300dpi because of the limitations of the medium.
