temp. lowering job and raising back w/o alignment?

[Silverblade]

Ok I want to drop my 97 explorer 2 inches by doing the TT and blocks but only for an hour or so to take a picture to see what it look like then I want to jack it back up the 2 inches(snow coming soon).

Because it is aligned for stock height if i lower it then bring it back up do I need to align it again?

If you notice in my sig i have done and undone the TT/lowering block thing a few times, because i can't decide which i like better. I hope it's not bad for anything. But going up and down has not affected my alignment at all. I never got an alignment after dropping it the first time anyways.
