Here is short video ( 7 1/2 minutes) on the comparison of Pixel Dimension vs Document Size. It can be sort of confusing with all the cameras and phones and Internet giving various pixels per inch. The thing to remember is how many pixels does the image have. And go from there.
The video starts with my having opened a document that is 8 x 8-inch at 300 ppi. We normally want to print our images with 300 ppi. And it goes on to show images with 96 ppi, 72 ppi, and 180 ppi.
I hope that this will help you understand this a little better. Wouldn't it be nice if it was all given at the same ppi from the beginning?

Welcome to EarlK Design!
The EarlK Design blog consists mainly of entries that show how to do things using Adobe Photoshop that I hope you will find helpful and give your creative mind more tools to work with.
I use Adobe Photoshop CS6, and sometimes Adobe Illustrator CS5, Lightroom 5, and Corel Painter X. However, I believe that much of what I show can be done using Photoshop Elements.
