Not necessarily true -- it depends on how intelligent your photo software is.
Many software packages (Photoshop and ThumbsPlus are two examples that come
readily to mind) allow the option of re-saving "with original quality" when
using JPEGs or other "lossy" file formats. No further compression occurs. I
archive a number of graphics that I'm working on for a (non-camera-related)
project using JPEG, and have been doing so for several years now, with no loss
of quality.
You just have to be aware, that's all.
