A family of Microsoft word processing software products for creating web, email, and print documents.
Instead of using the Format Painter, I would suggest using the built-in shortcut keys for Copy Format (Ctrl+Shift+C) and Paste Format (Ctrl+Shift+V). These have the advantage that once the format is copied to the Clipboard, it can be pasted indefinitely, even when there are intervening actions, until it is replaced by another format. But if you have very many images to do, a macro might still be more effective.
