Resize an Image in Contribute

1. Click on the image you want to resize.
2. Click on the Resize tool at the top of the document window, or click the "Format" menu in the toolbar across the top of the Adobe Contribute application, then select "Edit Image", then select "Resize".
3. Three anchors appear, which you can drag to resize the image. The one in the lower right resizes the image proportionally, while the other two change only the width or the height.

Note: Changing the size through Image Properties only resizes the display of the image, it doesn't resize the image itself.
