alt tag in Firefox

How do I write the css code for alt tag so that it shows up in Firefox? The line of code below shows alt tag in IE just fine, however, nothing appears in Firefox:

<div align="center"><img src="../images/ruarkcherrydresser.jpg" width="480" height="366" alt="Cherry Dresser" ></div>

Thanks for any and all help.

I take it you are reffering to when you cursor over the image. And BTW, alt is an attribute, NOT a tag.

Well thats IE being IE. The purpose of the alt attribute is to provide some reference if the image does not display.

If you are looking for information about the image to display when the cursor is moved over it, then this is what the title attribute is for.

Yeah like Geoff said, I think you are looking for a title attribute, not an alt attribute...Good Luck!!

No, in Firefox, the alt attribute is the one that should pop up. I don't really know why Safari only has the little tool-tip when the title tag is in use, but alt is required, title isn't.

the code below will work in "most" browsers:-

<div align="center"><img src="../images/ruarkcherrydresser.jpg" width="480" height="366" alt="Cherry Dresser" title="Cherry Dresser"/></div>

do me a favour, can
you sent me a msg explaining this codes <alt><c3><marquee>

Take a look at http://www.w3.org/MarkUp/

<alt> is not a tag, it's an attribute of the <img> tag.
<c3> is not valid markup, possibly meant to be <h3>.
<marquee> see:- http://www.htmlcodetutorial.com/_MARQUEE.html

As stated:

Alt stands for Alternate text which says what theimage is if for some reason it does not or cannot be displayed. Title is used to display a title for an object i.e. links in case they are not descriptive enough etc...

An alt attribute alone will not make a box pop up in Firefox. Firefox requires you to use the title attribute, so personally, everytime i'm using an image or even a link, I make the alt tag and then copy and past it again but change the second alt to a title.
