They're randomly generated as required- 36^4=1679616 possible sets of characters, plus differences in fonts etc.

That's what I think anyway :S

I donít think is so many because it seems not to be made by a program and how many a man can make? I estimate they are at most 10000. The real number can be lower then this because it seems they repeat often.

you could make some screenshots to each individual character in each font...there shouldn't be too many...i don't think that more 4-5 fonts are beeing used. Also not all alfanumeric characters are beeing used. The diffrent font size make no diffrence in char recognition and neither does the rotation agle. So if you were thinking of how easy it would be to make an auto program...the answer is medium compexity. The capcha in the clicking zone is however next to imposible to autorecognize

Actually they are some auto clickers and the alphanumeric system is hard to brake then that in the clicker area (in my opinion). The admin need to make a system more hard to brake and to do this they have to get rid of all image (a imagine base system is easy to brake, and only make life hard for honest players).

The images are entirely program-generated, although obviously a human has designed the basic layout of what it will look like. If you see the image repeated - on recruiters, for example - it's because the pages are generated at the same time and the randomiser is seeded the same way each time, as far as my understanding goes anyway.
