In viewing an image on the screen, most images look quite pixelated because the viewing monitors usually are showing a 72 ppi. This is more pronounced of course when you zoom up an area of the image. But, some images look more pixelated than others. Is there a reason for this? I realize that different resolutions and line screens can be applied to "print output" but I thought ppi was a standard 72 ppi for "all" monitor viewing. Thanks for advice.

The ppi of a monitor is irrelevant. An object 100 pixels in width will take 100 pixels in width, wether a 15 inch or a 24 inch monitor.
And no matter it is set for 640x480 or 2040x1280.
If it is "pixelated" there's either something wrong with the image (ressed up?), or you're too close up the screen.

Or you're viewing at greater than 100% pixel size.

Also 72 ppi has not been a standard since the Mac Plus/SE/SE30. It never was a standard on PCs, and no longer is standard on Macs (although you might have it as an option there). PCs generally have a screen resolution that is higher ... I use 96 as an average although, as others have noted it depends on the image resolution and the physical size of the monitor.
(Trivia. A school I worked in had spent some big bucks to buy a 21 inch monitor. Unfortunately, the accompanying graphic board was limited to a maximum resolution of 640x480. Pixels as big as your fist (well, almost).)

Thanks for the feedback guys. I hear your point Don. It wouldn't be the first time people understand "parts" of the issue and then try to whack their way through it from there :)
