Raw fMRI scan images

Thank you again for sharing this data.
I wonder if the raw fMRI scan image files are available online somewhere. 
I wanted to use my own procedure of fMRI preprocessing pipeline, however I can only download the already parcelated fMRI time-series.
To confirm, am I correct on the aforementioned enquiry or I still can find the fMRI image files on your server? 
I know the raw images should be of hughe size, but if site-20 is available, that would be much enough.

Thanks,

Fuad
