@cobraa – Please feel free to ask general questions in regards to NextGEN Gallery via your member’s area support request as well … although I am not certain what you are wanting to make changes to.
Have you looked at the Gallery > Gallery Settings page? This is where you can set “global” options for displays being inserted afterward.
If you need to change an existing display, you can simply go back into the post/page, click on the preview image to re-open the IGW modal window and then look at the customizations accordion panel to make changes to that specific display.
Thanks!
– Cais.
