The issue is the optimization, because cameras take such large pictures, you need to resize them so that they can be easily shared online.
So no matter what you do your always creating two versions of an image, the "original" one and the optimized one. And as far as the cryptography is concerned those images don't share any resemblance.
We think of them as the same image because the optimization process tries to preserve the picture, But an "optimization" process could also easily be putting it through Photoshop and modifying the image.
The reason I mention all this is to illustrate the point that when you publish an image online, you must make an "optimized" copy of it that is not the original. And since the public only sees the optimized copy, it's that version that has to be backed up somehow
So even if you signed the original or backed it up on your phone it wouldn't matter, because everyone else will be looking for the optimized version
Anyways, sorry for the long reponse but it's difficult to explain
