Did anyone see my other post?

" A 1200x1200 pixel image has the same number of pixels no matter what the dpi "

Raven - If you are talking 300 DPI; and referring to 3" square inches of print, then you are talking about a lot more pixels than if you were referring to that same 3" square inches of print at only 72DPI.

In other words the data that defines the pixel is there to be defined by the literal Size and DPI attributes an image holds.
