Well, not screwing it up, but, it will suffer a little degradation both in
the rotation and saving. Read the thread and study the links, it's
explained prety well. Basically, if you are going to do anything to a
jpeg(jpg) besides viewing it, first save a copy in a lossless format, then
open that copy and work on that, then you can save a copy of that in jpeg if
you need it for web/mail use.

This is very true, bottom line is are you happy with the result? However,
it is a good idea to get into a good practice from the beginning and that
isn't difficult.
