Step 1: read an image.

Step 2: put it in a loop.

Ask general questions, you get general answers...

Try to be more specific. Let us know what you have and where you get stuck.

I don't have IMAQ installed currently.

Why do you try to open an .avi when your files are .jpg?

My purpose is to track the motion of a particle in the avi video. But this cannot be achieved in this VI. So I'm going to make the video into a lot of pictures and then let this VI analyze the picture instead of the video. Now, I can't even read pictures continuously, so I wonder if you can solve the underlying problem directly

Have you seen "LabVIEW\examples\Vision\Files\Read Write AVI With Data.vi"?

That should give you a good start with reading frames from an avi.

Help>Find Examples.. Then search for "avi" should show it (if IMAQ is installed).
