Why ALT tags don't show on Firefox images

[Mike Grigsby]

I wondered why my image tool tips weren't showing in my apps:

Firefox won't display an image's ALT tag unless you add a TITLE to it.

So this tag won't display a tooltip:

<img src="somepic.jpg" alt="This is my dog" />

This one will:

<img src="somepic.jpg" title="This is my dog" alt="This is my dog" />

I don't believe the title has to match the ALT tag--you simply have to have one for the ALT tag to work.
