How do I get Dana to enter her frog in the contest?

Hint 1 of 7:

You won't be able to handle this problem for a while.  At least wait
until the end of the day (game time) before reading further.

Hint 2 of 7:

You will need to convince Dana that you really are her friend, and not
just asking her to enter Gigi so Horny can win.

Hint 3 of 7:

Do you have any proof of your friendship?

Hint 4 of 7:

You had a chance to take a picture in the pizza parlor.  That photo is
good proof, but not good enough.

Hint 5 of 7:

Dana might want to display the picture so that everyone can see it.
