Would a password combination of images be stronger for users login regarding keyloggers?
Yes, it would be stronger... a little bit. That is not saying much.
A keylogger will catch only the keystrokes and not the selected user images, right?
If you want to be technical, a keylogger logs keys. In the real world, many "keyloggers" also log things other than keys. See these answers:
Can I protect against keylogging by using the mouse?
How easily are keyloggers foiled?
Malicious software that only logs keyboard strokes rarely exists in the wild. Most key loggers for graphical interfaces (e.g. Windows) are more sophisticated and log all user interaction including mouse, copy and paste events by hooking into the operating system.
Key loggers are normally a small subset of a rootkit that may also include the ability to act as a man-in-the-middle (MITM) and capture your credentials or session information without logging any key strokes.
The best way to foil key loggers is not to have them.
Is this enough to defeat keyloggers?
That all being said, the sort of mitigation you're talking about may have some small ability to discourage those black hats that are harvesting passwords en masse, since it will be harder for them to publish and collect payment for their findings (it's pretty easy to supply your customer with a CSV file of user names and passwords, it's a bit more work to include images and mouse clicks for each and every victim). This is not much of a reason to go to the trouble, to be honest. If you are being targeted individually, then the scheme you're talking about would offer almost no protection.
Images still have a role in authentication-- you can use them to help your users identify phishing attacks by providing personalized images-- but in terms of defeating keyloggers, you really need to go with OTP, i.e. with a key fob or out of band. Even OTP isn't going to protect against real time attacks but it is a pretty good way to protect against password harvesting.
