Problem with Nextgen gallery

Hello WP Team,

I have Nextgen gallery in one of my section in website where it is working fine and for other which is not working (Popup is coming, but image does not show up).

Issue seen in this link:
https://amritavidyalayam.org/photo-gallery-2/
In this section, popup comes and it resizes but image does not shows up.

Same gallery which is under news and events:
https://amritavidyalayam.org/sadgamaya-summer-camp-2014/

Could anyone point out what might be the issue?
