search engines cannot `see` images, proper Alt content will help them to better understand and index images.

Tips:
1. always add alt attributes to images. Alt is mandatory for accessibility and for valid XHTML.
2. words used within an image`s Alt attribute should be its text equivalent and convey the same information.
3. use a human-readable caption and descriptive text around the image.
