Learning how to change or resize the pixels of a photo in Adobe Photoshop Elements has been a chore for me. I never knew how to get the pixels that were grayed out available for editing. I finally found out what to do! This works on Photoshop or Photoshop Elements.
Changing Pixels in Photoshop
Click on “Image” in the above toolbar; then click “Resize” and “Image Size”. If the pixels are grayed out, just check the “Resampling” box below and you will then be able to resize the pixels. If you then wish to change the resolution of the photo, uncheck the “Resampling” box and change the resolution. However, changing the resolution will change the document (print) size.
To learn more even more, check out this great video tutorial I just found.

What’s the difference between resizing pixels and changing the resolution?

My understanding, from my recent research, is that pixels are the elements used to capture an image on camera or film. They appear as dots: (DPI = dots per inch). It is the density of the photo which shows more details, which is known as resolution.
Resolution: (PPI = pixels per inch). If the resolution is too low you will see the dots. Therefore, when adjusting the pixels you may wish to adjust the resolution. If you are using your image online there is no need to make the resolution any larger than 72, or you will just be making the file larger for no reason. Anything larger will not make the image appear any better. For printing, multiply the resolution by the by the print size, e.g., an 8 x 10 at 300 DPI (pixels) requires a resolution of 2400 x 3000 (magazine standards). Any sized photo for printing on an inkjet should have between 170 and 250 DPI.
Though many people refer to everything as DPI, cameras are measured in PPI and printers in DPI.
