Ok lets get back to the topic title. " Resolution of Newspaper Photographs" When I read that, the 1st impression I get is how many dpi does Newspaper print in. Not like 640x480 or 1600x1200.
When I work for web I optimize my images to 72 dpi. When I need something done for high res, I submit my files to the printer as 300dpi (if its a raster job). If it's just vectors I submit it as an EPS file. So that where to me dpi is important.
So for me I don't post a 180dpi file on the web to be viewed by a browser cos it only reads 72dpi. And I cannot submit a 72dpi file to be printed by the printers. There are some tricks u can do to increase an already low dpi file to be printed, but of course there are some in herent quality loss.
So thats the direction I'm coming from.

This is really unnecessary Do note that the important "dimensions" is the 1280x1024, rather than the DPI.
Hopefully, you didn't have to repeat the process everytime you change to a bigger monitor.
