Display gallery above title on single page

I want to display the native wordpress as a slideshow on above the Headline at the singe page.
I already replaced the standard wordpress gallery with my own code to support a jquery slideshow.

I used the code from the following Page:
https://stackoverflow.com/questions/19802157/change-wordpress-default-gallery-output

But now the Gallery is still display within the content (where it is placed in the editor)

How can I remove the gallery from the content and place it above Headline
