Return to the Source view tab. Notice the open and close table tags and. Notice the open and close table row tags and -- there are two sets because there are two rows. Notice the open and close table data (cell) tags and there are four sets because there are four cells (two rows with two columns each).

Drag from the Image icon in the Toolbox to between the first open cell and close cell tags Remember that if you do not have the Toolbox, you can get it by going to View/Toolbox on the menu

Click on the image so it appears in in the Properties Window on the left. Scroll to the src property (attribute) and click on the ellipsis (…) button that appears after you click in the cell next to src Remember that if you don’t have the Properties Window, you can get it by going to View/Properties Window on the menu. (Properties Window is near the bottom of the list.)

Use the dialog to select the abraham.gif file and click OK. It is really convenient when you are just starting to make webpages to put the image file and HTML file in the same location.

Give the Lincoln image an onclick event: And add the corresponding script section and function to the head.

Give the Abraham iframe an id attribute (ifAbe)

Add the code document.getElementById("ifAbe").src = " to your function. Make the src of the iframe equal to “”

The effect is to eliminate the iframe src (youtube video) until the image is clicked.

Repeat for Martin: give iframe an id, give image an onclick, write function to handle onclick
