Well, the whole idea of Gentoo is that there are no disk images. You compile everything from scratch. It takes ages, but in the end all the code is hyper-optimised for your hardware, which is fairly important for slow devices. If you're asking about the images used in benchmarking in order to reproduce the results, though, then it's another matter.
