*update - it appears this issue has not affected / been fixed for some but I will leave this post up in case people have image issues!*

If you blog with Blogger you might have noticed your formatting has gone a bit crazy! All of my photos were left aligned and no matter how many times I tried to format them they just wouldn't stay centred. If your photos aren't behaving you might want to give this a try...

Here's the fix:

Go to Template


click Customise


click Advanced


scroll down to Add CSS


Copy and paste the following:

.post-body img {
       display: inline-block !important;
}



I would advise adding the code at the top of the box (some people report that works better).
Then click Apply to Blog


Hope that helps!
