Any way to put the front end uploader on all new post and pages automatically?

Something along these lines should do (not tested):

Put the following code in your functions.php:

add_filter( 'the_content', 'my_append_fu_form', 20 );

function my_append_fu_form( $content ) {
    // Put the shortcode call as you want it to be as a do_shortcode parameter
    $content .= do_shortcode( '[fu-upload-form title="My Frontend Uploader test"]' );
}

i have a problem putting it as i did it . wat i get is empty home page

Check your error log for any Fatal errors, looks like a syntax error to me. Also try this snippet

add_filter( 'the_content', 'my_append_fu_form', 20 );

function my_append_fu_form( $content ) {
    // Put the shortcode call as you want it to be as a do_shortcode parameter
    $content .= do_shortcode( '[fu-upload-form title="My Frontend Uploader test"]' );
    return $content;
}

I just tested it, it displays well but upload is not going to work because javascript is targeting form ID and id should be unique. I made a fix and will release it with the new version.
