i am a novice user of wordpress and have just installed

Hello i am a novice user of wordpress and have just installed Spirit theme via the WPMU Dashboard and wanted the images also to be installed (dummy data/images). How do i have this also installed or am i not allowed? currently it is showing up as all blurred and pixalated.

If allowed to use the images then i will be downloading the other 2 themes also and there images. Please let me know the process- step by step. Thank you.
