There is 50 MB of free space in a free blog hosted at wordpress.
Many themes only takes 0,1 MB space.
I know how to upload themes to an EXTERNAL blog at my webhotel with my ftp client
to the directory: wp-content/themes/
But I wonder if it's possible to upload a theme to my free blog hosted INTERNAL at wordpress.org ? <EDIT> wordpress.com </EDIT>
It seems only possible to upload pictures?
