How Can I Make Text Behind An Image Before The Image Has Loaded?

Often, I can see some text in an image's place before the image has been loaded. How can I do this myself?

Solution 1:

Put the text in the image's alt attribute

<img src='images/image.png' alt='My Text' />

Solution 2:

That's represented by the image's alt attribute (which, by the way, is required):

<img src="image.jpg" alt="Alternate text for image">

And in case you're wondering, no equivalent exists for background images in CSS. There shouldn't be, anyway, since background images are purely presentational.
