Not a problem.
Most free avatar makers usually get discontinued unfortunately.
My script was refined over 6-12 months.
I made it freely available as a hosted service.
Originally you could not buy it, but after a few emails I finally decided to allow others to use it, so I started to sell it.
And yes, it can be used for avatars.
ADVERT SNIPPED
So if you wish to save yourself the time and use a codeset that was stress tested to handle 150,000 people a day.
Otherwise if it's just a school project, you can research all that stuff on the net and eventually build an avatar maker. It just takes time.
have fun
