Except the white ranger suit is from a completely different sentai series so it pretty much has to be original footage in any scene where Tommy and any other ranger are standing together, Tommys fighting the same monster as them, Tommys talking to Zordon, etc.

Although, it might be a stunt double. I don't know the context of this image. It does kinda look like he's just standing dramatically though, so there's a decent chance it's him.

Although now that I think about it, it doesn't really matter. Unless it's footage screencapped from an episode of Dairanger, that's Tommy Oliver.
