How can I get root acces?

[Tompa59]

I have been playing with putty and can see that I can not change directory to reach the var/www-folder.
That propably has to do with root access?

Please help with my newbie-struggle to copy files from PC to Moode.

I realy would like to have my added radiostations to show their thumbnails.

My files are on my Windows PC C://jpg/  (several .jpg files)
I would like to copy all of them to var/www/images/radio-logos/
