I know that one solution is to enforce justified text when converting books in calibre then turn justify Off on the kobo. But for some reasons I'd like to find a way not to have to do that on some books. I'm ok with editing books and using a regex-find-and-replace, but I'm not very good at css. Is there some property that I could inject that would center images even in kobo-justifed mode ?

First let me say that if you want to understand and control styling in your Kobo epubs/kepubs you really need to understand how HTML and CSS works. You don't need to be an expert but a basic understanding (and a willingness to learn more) is essential.
The problem you're running up against is the Kobo firmware's built-in CSS overrides used when you use the sliders and buttons in the [Aa] menu. Override CSS for kepub is more aggressive than the override CSS used for standard epub.
In the scenario you've raised the default override CSS for kepub text alignment is
Code:
div, p { text-align: %1 !important; }
so if you're wrapping your book's HTML <img> tags in a <div> or a <p> tag, then any
text-align:center CSS styling is going to get overridden by whatever alignment button (left/justify) you've selected in the [Aa] menu.
You can combat this in one of 2 ways:
- If you're a user of the kobopatch system you can make the override CSS above less aggressive with a patch to the firmware. See patch Un-Force user text-align in div,p tags in KePubs
- If patching is not an acceptable option then you could try wrapping your book HTML <img> tags in any block HTML tag which is neither <div> nor <p>.
Personally I choose option 1. I have not tried option 2 (
and it will probably make standards purists shudder 
) but see no reason why it wouldn't work. Obviously you'd need to do it for every book.
