Still images flickering premiere pro after rendering [NEEDS TO BE DONE BY FRIDAY!!!]

I've been working on a project for a while now, but now there's been a problem which I simply can't resolve.

The video in premiere pro you cant see the flickering there until you've rendered the video itself.

and also a another thing that it's only some of the images in the video who are flickering,and all are the same type of images (JPEG), downloaded form the same site as well.

And I simply dont know why this problem appears, I've tried changing format, from mp4 to mov, and with different presets as well, and it still keeps appearing.

Please, I'm desperate, I need this to be done by FRIDAY THIS WEEK!

I hope someone knows a solution on this problem.

I'll upload a small part of the video to see what the problem is about.
