Challenge

I got this email like years ago. But I never found time to realy look into it. Will start looking today. :P Tell me if you can find all! Hehe...

/This is a challenge for you to solve, in those pictures have 7 dolphins and 7 hearts, can you find it?

If you can find 3: You are just like average people.
If you can find 4: You are getting close to smart.
If you can find 5: You are pretty smart.
If you can find 6: You have excellence imagination and vision.
If you can find 7: You are the best./

7 Dolphins?

7 Hearts?

Good Luck people! :)

p/s: (updated after looking) I think I found 7 hearts and 7 dolphins, though the last find of each could be something else haha...
