No sure what is going on...
But I've just used the quote function to see what was in your post as the photo code was 'invisible'.
I then compared that to the code in the visible photos in one of my posts above.
The difference appears to be ibb vs i.ibb at the start.
So if I add "i." infront of the code you posted I get this.
No idea why it is so small, but at least it is better than nothing.
