How can I resize an image within a table in Pages
You can reshape the image in a table by playing with its dimensions on the sidebar. After clicking on the image once, click on the "Format" icon on the toolbar at the top of Pages and play with the Width and the Height numbers in the "Size" option in the "Arrange" tab that appears on the sidebar. Reshaping is done more freely if the "Text Wrap" option in the same tab is set to "None".
