What should I do in order to enable my image gallery to show more than 9 pictures?

So basically I have 100 pictures in a file , i then added them to my code, Afterwards I ran the emulator to see if all 100 images were showing within the image gallery I created instead it was only showing 9. So I would like to know what should I do to fix it.

The code is on this site: Image is hiding at the corner of the screen when I run the emulator - pictures aren't showing at all - The image list on this site is less , the above 100 images were added a couple of hours ago.

At this current moment I am still trying to figure out what to do, would you kind experts from around the globe be so kind to help me resolve this issue please. Thank you much is appreciated. Hope to see your comments soon :)

Thank you
