Editing the .php files, adding pictures Threat To Creativity

I have edited the sidebar to try and change the “WordPress” link to “WP”. No matter how many changes I make and FTP the sidebar.php code to my blog site, NO CHANGES will take effect.

I can change the CSS file, FTP it, and the changes are immediate, but when I edit the header.php, sidebar.php, footer.php files the changes will not take effect.

I am missing something completly and it driving me crazy.

And could you please tell me where to find the code that allows images in your posts??
