To Optimize your use of images:
Images may seem like a straightforward component of your site, but you can optimize your use of
them. All images can have a distinct filename and "alt" attribute, both of which you should take
advantage of.
The "alt" attribute allows you to specify alternative text for the image if it cannot be displayed for some
reason.
Why use this attribute? If a user is viewing your site on a browser that doesn't support images, or is
using alternative technologies, such as a screen reader, the contents of the alt attribute provide
information about the picture.


Avoid:
• using generic filenames like "image1.jpg", "pic.gif", "1.jpg" when possible
(some sites with thousands of images might consider automating the naming of
images)
• writing extremely lengthy filenames
• stuffing keywords into alt text or copying and pasting entire sentences
Avoid:
• writing excessively long alt text that would be considered spammy
• using only image links for your site's navigation
