Simple way to rotate images

I have received an extensive set of family photos that another family member scanned to their computer.
Unfortunately, they did not bother to orientate them very well.
I am trying to find the simplest method to rotate these images.
I started with Automator and soon determined that any photo that was rotated by Automator had its file size substantially increased. I would like to prevent that if possible and determined that "sips" will keep the files close to their original size.
I found that Hazel could do the job better by calling a shell script that would execute a "sips" command.
I don't want to move the files that need to be rotated to another folder and then move them back. What I would like to do is add a "color" tag to each file that I want to rotate and then enable the rule to run on the folder when the file has been "colored".
Does this sound plausible and can Hazel do it? I have tried it but I can't seem to make it work.

Jim P.
