The idea is that a phishing site (especially an untargeted one) wouldn't know which image to present to you
And that you somehow magically remember whether you chose the yellow flower or the green flower.
If uou use it regularly, you will notice the change if you are paying attention. You could also store it as a note in your pw manager.
No security concerned user will fall for a pishing site nor waste time remembering it, and others won't care eitherway.
I disagree with most of this. But even if you are correct, at worst it's harmless.
It's extra complexity (technical and mental), and is also an indicator of how security controls are designed (in this case: "bring the kitchen sink!").
I don't think it's all that complicated to have a chance at catching/preventing phishing sites by a user not seeing the picture they normally see whenever they log in.
How does it work, when you enter your username a special image is displayed? The phishing site can just POST the username you enter and grab the right image, no? Not really sure what it's supposed to prevent...
One thing it does is it helps prevent you locking someone else’s account due to having similar usernames.
Not really a "security" feature though! Kind of an anti-feature, to workaround a DoS that people trigger accidentally 
True, but it fixes two simultaneous problems and reduces tickets & customer stress/helpdesk stress. 1 - MY PASSWORD DOESN’T WORK!! 2 - My account keeps on getting locked out even when I’m not trying to get into my account! OMG HACKERS! Not every design feature is about security
This is fair (I guess even FB does something similar with profile pics), it's just that in this case the feature is explicitly advertised as security hardening.
