ISO file to contain zip/rar of graphic files - how to handle

Hi, everyone,

I have downloaded a large iso file which is supposed to contain a series of a hundred (over 120) zip/rar of graphic files (not smut or porno!)

I cannot open this file with Win Rar, if I click the icon of this iso, my Nero Burner will be activated to burn a back-up CD (which I did). But after that, I still cannot see any zip/rar file on the back-up CD

What should I do to open this iso file to extract the zip/rar (eventually to get to the graphic files). I am using Win RAR 3.51 32-bit console version.

Appreciate your help to get this problem solved.

Thanks you all for your very helpful assistance !

Open the original download with ISO Buster.
Myabe that will work.
Or the original was put together wrong.
