Always make the source of a frame an HTML document
Access note: This simple example uses a table and an image to simulate the look of a page created with FRAME markup.
The accessible way to insert content into a frame is to make the frame's source an HTML file. In this case, source for the frame with the picture of the house should be:
<FRAME name="picture_frame" src="home.html">
where "home.html" should contain the following:
<IMG src="home.gif" alt="Picture of a house.">.
If you make the frame's source the image file itself:
<FRAME name="picture_frame" src="home.gif">
then you can't provide a text equivalent for the image.
