I'll write a stepwise guide, the problem is because this application isn't ready for Extras yet, so people watching this thread don't think you need to do something similar when you'll be using your N900. The N900 is super user friendly :-) 1) Install rootsh (you can find it in the application manager). 2) Save this file with the browser to the "Documents" folder. 3) Open the X Terminal application. 4) Write "root" (without the quotes) in the terminal, press the "Enter" key. 5) Write "cp /home/user/MyDocs/.documents/libgstximagesrc.so /usr/lib/gstreamer0.10/" (without the quotes of course, and note the spaces), and press the "Enter" key. 6) Close the X Terminal and forget it ;-).
