The drag and drop convenience of Microsoft FrontPage 98 makes you more efficient but leaves some unprofessional touches to Web pages.

Newer browsers display the ALT text as a type of tooltip when the user passes the mouse over the image. Rather than leaving the useless and unsightly default text, make sure you write text for the ALT attribute with the same care that you apply to the rest of your page.
