sometime the alt attribute doesnt work on some browsers..how to fix it?

Answer 1

The 'alt' attribute is fully supported by all major browsers. I don't know about Android versions. What browser are you using?

Answer 2

using Firefox on windows.

Answer 3

Firefox and other browsers require the use of the 'title' attribute in order to display balloon text. They follow the W3C standard. The 'alt' attribute shows an alternative text when an image cannot be loaded.
