Best Practices: A Closer Look at the Image Realities
There are two three important factors to consider when selecting and printing images for an assignment:
Narrow your results by the usage rights drop down menu and select the appropriate license:
Google Advanced Image Search
select the Narrow your results by ... image size: and the any size drop down menu.

Pixel dimension ÷ 250 = largest size in inches to print.
1024 pixels ÷ 250 = 4.096 inches
