At least partly wrong! It's possible to rotate (in 90 dgree steps) JPEG 
files without doing a decompress/recompress (which loses quality) - it can 
be effected by rearranging the compressed JPEG data. It's also possible to 
crop on block boundaries in a similar way. GraphicConverter will do lossless 
rotation - Photoshop won't. If you have a search on google you might find 
some C source for doing this, though that probably wouldn't help you in 
Rev...
