This looks like a great fit for Page Transitions. For the confirmation form, it looks like they are displaying a new form on that page.
What you could do is redirect from the form with the transitions to a new page that contains that new form. You can then use Easy Passthrough to pass values from the first form to the second form. The user can then double-check any of the values and make changes as needed.
We don’t currently have support for displaying an image/text mid-transition. If you’re a Gravity Perks customer, drop us a line and we’ll be happy to pass it along as a feature request to our product manager.
I’m sure this is simply a matter of personal opinion, but when the form paused mid-transition I actually thought there was something wrong with the form. It confused me as a user and after a moment I tried clicking in the image thinking that it was supposed to be interactive. Not trying to talk you out of that interaction, but that was my experience.
