Posting "Cleaned" Images

I think I asked this before, but I can't locate the thread,...
Anyway, without creating any "duplicate" issues, I've noticed over time a lot of "classic" celebrity pics have become discolored from data degradation.
I've run a few pics through my images software (Irfanview),doing nothing more than running the "auto adjust color" feature, No re-sizing, no manipulation, no photoshoppping.
Here are a few examples:
Original: www.listal.com/viewimage/5877992
Auto cleaned: www.listal.com/viewimage/5909162
Can I post my cleaned image and mark the old image for deletion?
Please advise and thanks in advance.
