While inches and millimeters are appropriate measurements in the
real world the density of computer screens and printing methods
call for a different measurement. Digital images are measured in
pixels. 4″ x 6″ inch file for the web that measures 400 pixels
by 600 pixels 4″ x 6″ file for printing that measures 1200
pixels by 1800 pixels The following chart shows us that pixel
dimensions are the key measuring system for digital images. The
more pixels = more information = larger file size and better
quality image 1000kb = 1mb kb, kilobytes and mb mega bytes is
how much information is contained in the file. For a high
resolution file suitable for printing its gonna be 5 or 6 mb but
for the web it would be around 100 kb. We try to keep the file
size lower for the web so it doesn’t take too long for the image
to load on your computer screen. One way the web developer does
this is by using jpeg format. Jpeg is a compressed format. It
shrinks the final file size while maintaining the number of
pixels. It’s like a pa
