Add buttons (images) to gallery overview for editing photos

[chross]

Describe the issue
Hi! I want to display a button for each thumbnail image in the gallery that allows the user to edit the corresponding photo. However, when adding the images they will also be displayed as part of the gallery. How can I exclude images in a <div id="nanogallery2"> div to not be part of that gallery?
