Answer 2

Most teacher's kit to the textbook will have these included.  Perhaps you can ask a company for a free sample to preview.  Also, with the proper materials (you can purchase blank, heat-sensitive transparancies) and equipment (copy machine) you can convert a picture you find in a magazine into a transparancy of your own.  Ask around, other teachers may share. "Hooks" can also be a super question on the board or a live fish in a bowl for example.
