Heads or Tails - Stuck!

[mintypython]

I'm drawing a blank on this. I've got an idea or two but I'm not getting anyway. Can anyone provide a hint or nudge?

You're looking for a word that could end the first word or start the second word.

[mintypython]

Darn, I had a feeling that might be the case. I shall continue to ponder...

[mintypython]

Nnnggghh. Still can't think of anything to fit in between. Can someone be kind enough to give another nudge? Pretty please?

[rich]

It's a homonym for the missing parts that makes a word.

[mintypython]

Still stuck. I'm assuming the first picture is a word of 4 letters and the second picture is a word of three letters. But I can't yet find anything to go before or after the second picture - there's a few things that can go before/after the first picture but they're not enlightening.

Any further cryptic hints from anyone?

Your guide could improve his delivery.

Work on sounds not spelling - I think from what you've said, you've got the right 2 words.

[mintypython]

OH BOY. Finally got it, but that was painful. Ouchie ouchie ouchie.

I had the right start and end words, but it just took me ages to fine the link between them all.

As a clue to everyone: _ _ _ _ [x] _ _ _ , but work on sounds.

Donkey's spelling is not perfect on this one.
