I can still see some of the images on my screen form my previous login. For example I can make out the mouse cursor and various frozen icons.
I have attempted to reboot it several times and the images do not go away.
I have also tried taking screen shots of the images however they are not shown. Perhaps this gives some indication of the problem?
Welcome to the Apple Support Communities.

If you Mac is on the vintage or obsolete list, parts are limited and may not be available, and you should consider a new Mac.

What you describe sounds to me like "burn in". It was common back in the days of CRT monitors and was a big reason screen saver were invented. I didn't think this was still possible with the modern Mac.
But, for future reference, you might consider to enable your screensaver or allow the monitor to shut down after a short time, rather then leave any image on the screen for a long spell.
Yes, I know, that doesn't solve your problem, but I only had $0.02 to spare for now. 😉
