How to install Viewers and Plugins?

[humanakeo]

I dont know how to install viewers or plugin for my ipod nano.

I downloaded gif viewer:
http://www.rockbox.org/tracker/task/3037?histring=gif

JPEG viewer vol+/-:
http://www.rockbox.org/tracker/task/7173?histring=jpeg%20resiz


And i downloaded some png viewer:
http://www.rockbox.org/tracker/task/6649?histring=png

when i downloaded the png viewer, there was a file called mypatch...it had no file extension(same for "JPEG viewer vol+/-")....what do i do, how to install it?

The gif viewer and the file was called viewbox.c. How to install it?

This isn't really appropriate for this section of the forums (which is for questions about how to install Rockbox itself). All the official viewers and plugins come with it. What you're linking are called "Patches". They require you to compile. See the SimpleGuideToCompiling page in the wiki for more information, and when you get specific questions please ask them in the compiling section. Thanks.
