Quick noobish question; if I'd like to try a different kinda loading image, how can I transfer the "indicator_update" -files, that i'm planning to use, from MyDocs to /usr/share/icons/hicolor/scalable/hildon?

I've tried using x-term and a couple of filemanagers to move the files, but I was wondering, that is there any easy way to do this kinda things, like can you get the /usr/... -folders visible on the PC, when it's connected in mass storage mode?

Thanks a bunch!
