I've been placing an alt attribute into my <img> tags, as the title says, and it doesn't seem to do anything in Fire Fox. I don't think it's another customizable Fire Fox thing like the post I made last week (at least I hope it's not! ^_^; ).

Does Fire Fox not support this? What's up?

Yeah FF doesn't display anything for Alt tags. instead, you have to use a 'title' tag

<img src="image.jpg" title="Text Goes Here" />

if you have a lot of images, just use a program like Dreamweaver and do a find and replace for 'alt' and 'title'

Cool, thanks just one more thing.
Does "title" work for other browsers or do I need to use both "alt" and "title"?

Edit:
Well I suppose I could just test it and see, duh!

It does work, marvelous!

in IE, Title will overwrite Alt...i don't know if this is true for Opera or Safari...if you want to be on the safe side, then you could add both

However, it is still recommended that you use the alt attribute for accessibility reasons and for validation reasons if you're using certain doctypes.

True. thank you for pointing that out

Just to touch up on what the others mentioned you, you can still combine the alt and title attribute to your image, and not have to worry about any quirks or one canceling the other out.

<img src="http://domain.com/image.png" alt="image" title="I made this image!" />

ALT is used in lieu of an image when it is not available. So if you link a picture of a cat on your website, and use the ALT attribute "cat," it will display the image if it's available, and if not it will display 'cat.'

Title is more so for a description when you hover over the image, or sometimes will coincide with another script (eg: Lightbox.)

It's not that it doesn't do anything, or isn't supported; while the image is downloading, FireFox will display the alt text, and if it's still there when the page finishes, that means you mistyped a URL.

It doesn't mean that you mistyped a URL. It could be a number of reasons:
1.) Wrong URL to the image
2.) Image is not responding (eg: the website is done, etc.)
3.) Just doesn't exist
4.) Et al
