How to resize a photo in TextEdit? When I add photos to TextEdit, they sometimes  appear too big, and I want to make them smaller.

How can I resize or modify photos in TextEdit?
TextEdit has no direct image editing options.

You can, though, once you've added an image into the document, double click it to open it with Preview. 

Through Preview you'll be able to perform some basic image editing such as size adjustment (Tools / Adjust Size) or adding figures or text (View / Show Edit Toolbar).
