1. File Naming Technique

2. Unique File Names
Provide a file name that will give you an idea about the contents of the file
Example: feedback_button.gif
NOT: button3.gif
File name should make sense to others
Example: class-pet.gif
NOT: roo-roo.gif

3. Use Lowercase Letters Use all lowercase letters
Do not use mixture of capitals or ALL CAPS
Example: class_picture.gif
NOT: Class_Picture.gif

4. No Spaces in File Name
Use a hyphen (-) or underline (_) in place of spaces
Example: my-dog.gif
Example: my_dog.gif
NOT: my dog.gif

5. Use Letters and Numbers Only
Use only letters and numbers, no special characters
Some special characters are not recognized by web browsers
Example: my2friends.gif
NOT: me&friends.gif
