You can mask an image using a shape, such as a star, instead of a rectangle.
Note:You can’t mask images you’ve added to the photo grid of a Photos or My Albums template.
On your webpage, select the photo you want to mask by clicking it.
Choose Format > “Mask with Shape” > [shape].
The chosen shape appears on top of the photo.
Fine-tune how the image appears in the shape:
To position the mask over the area of the photo you want to show, drag the image or select the mask and drag it.
To rotate the window, hold down the Command key as you drag the selection handles.
To zoom in or out on the image, drag the slider in the Edit Mask tool that appears below the image.
To resize the shape, select it and drag any of the selection handles. Shift-click as you drag to retain the proportions of the shape.
To view the image in its masked state, double-click the window. Double-click again to reveal the whole image and continue fine-tuning the mask, or click the Edit Mask button.
You can double-click a masked image at any time to reveal the original image.
When you’re finished, click outside the image or press Return.
At any time, to start over and begin to mask from the beginning, click the Unmask button in the toolbar at the bottom of the iWeb window.
You can also mask an image by dragging a photo from the Photos pane in the Media Browser to a shape you’ve already added to your webpage. Click the Edit Mask button to modify the mask if necessary.
