DPI in Photoshop

[Jack Winberg <jwinberg1@xxxxxxxx>]

Hi Folks:

An image file does not have any inherent resolution, JUST dimensions, 
strange as that may seem.  Individual software tends to "interpret" those 
dimensions as a particular DPI.  Photoshop tends to "see" images as 72 DPI 
when freshly opened.  Just adjust both the size and dimensions to suit YOUR 
purposes (web, monitor, or print) and all will be well.
