Duplicate 'Copy' jpeg images a waste of time and space!

Dear Sirs
Can you please tell me why, when adding some further information like borders and titles, to a hi-res jpeg file I can, no longer, just 'save' the additional work into the original jpeg as was possible before your IT guys got to it?  To save the amended file I now have to, 'Save a Copy' which means I then have two files the same file other than the additional work in the latter version!  This is not only stupid but it's additionaly time consuming and a waste of computer hard-drve space and my time!  This is just a total nonsnse which makes no sense what-so-ever; it's totally pointless and a ******* waste of time and gets me in a fume everytime!  Please, please, please bring back, 'Save' as it was; ie just saving additional work to a jpeg file!
Creating extra work to 'Save' a file isn't clever; your IT guys need to clamber down off their high-horses and get real for the real World!
