Oh definitely!!
Ideally, you would even prepare 'real' materials alongside your play back session. Eg., when you show the word for apple, and the picture for apple, and maybe even a video of people eating apples, you could even bring out a REAL apple! Break it, let your child smell it, taste it, etc!
For sure, variety would be best, if you can afford the time and energy that goes in the preparation!
That's why action words are great too, because you can get your child to participate in motion to the word.
And that's also why VIDEOS would always be more powerful than pictures. Hopefully, one day, our library would be so complete that we'd have videos of almost all the words out there.
