You have to be careful when doing simple stuff like this. Because some software packages will save jpeg images at greater compression rates (i.e. worse quality), than the original. I have had good 5 MB files, rotated them and saved them, and only later found out that they now are 1 MB files, without the software ever asking about compression rates.Andrew Rowlands said:I think that rotation of a .jpeg can, with some types of software, lead to loss.
